Chemische Eigenschaften

Copper is a reddish-brown metal which occurs free or in ores, such as malachite, cuprite, and chalcopyrite.

Physikalische Eigenschaften

Native copper has a distinctive reddish/brown color. Its first oxidation state (+1) formscompounds with copper ions named “cuprous,” also referred to as “copper(I),” and these ionsare easily oxidized with elements in group 16 (e.g., oxygen and sulfur) and elements in group17 (the halogens).Copper’s second oxidation state (+2) forms cupric compounds, also referred to as copper(II),which are more stable than copper(I) compounds. For example, copper in both oxidationstates can combine with fluorine: for copper(I) or cuprous fluoride, Cu+ + F- → CuF; and forcopper(II) or cupric fluoride, Cu2+ + 2F → CuF2.Copper’s melting point is 1,083°C, its boiling point is 2,567°C, and its density is 8.94g/cm3.

Isotopes

There are 32 known isotopes of copper, ranging from Cu-52 to Cu-80. Only twoof these 32 isotopes of copper are stable, and together they make up the amount ofnatural copper found in the Earth’s crust in the following proportions: Cu-63 = 69.17%and Cu-65 = 30.83%. All the other isotopes of copper are radioactive and are artificiallyproduced with half-lives ranging from a few nanoseconds to about 61 hours.

Origin of Name

Copper’s name comes from the Latin word cuprum or cyprium, which is related to the name “Cyprus,” the island where it was found by the ancient Romans.

Occurrence

Copper is the 26th most abundant element on Earth, but it is rare to find pure metallicdeposits. It is found in many different types of mineral ores, many of which are close to thesurface and easy to extract. It is found in two types of ores: (1) sulfide ores, such as covellite,chalcopyrite, bornite, chalcocite, and enargite; and (2) oxidized ores, such as tenorite, malachite, azurite, cuprite, chrysocolla, and brochanite.It is found in most countries of the world, but only a few high-grade deposits are costeffective to mine. Examples of some of its ores are cuprite (CuO2), tenorite (CuO), malachite[CuCO3 ? Cu(OH)2], chalcocite (Cu2S), covellite (CuS), bornite (Cu6FeS4), and chalcopyrite,also known as copper pyrite.Copper ores are found worldwide, in Russia, Chile, Canada, Zambia, and Zaire and, in theUnited States, in Arizona, Michigan, Montana, Nevada, New Mexico, Tennessee, and Utah.High-grade ores of 99% pure metal were found in the United States (and other countries), butmany of these native ore deposits have been mined over the past hundred years and are nowexhausted. Even so, many low-grade ores with concentrations of 10% to 80% pure copper stillexist and await a technology that will make them more profitable for exploitation.

Charakteristisch

Copper, a versatile metal relatively easy to find, has made it useful for humans for manycenturies. It is malleable, ductile, and easily formed into many shapes such as ingots, pipes,wire, rods, tubing, sheets, powder, shot, and coins. Although copper is resistant to weak acids,it will dissolve in strong or hot acids. It resists atmospheric corrosion better than does iron.One reason is that it forms a bluish-green film (called patina) over its surface when exposed tomoist air or seawater. This coating of copper carbonate and copper sulfate provides a protective layer for the underlying metal that makes it ideal for use on boats, roofs, pipes, and coins.The surfaces of some copper church steeples and the Statue of Liberty have now oxidized toform a pleasing patina.One of copper’s most useful characteristics is that it is an excellent conductor of electricityand heat.

History

The discovery of copper dates from prehistoric times. It is said to have been mined for more than 5000 years. It is one of man’s most important metals. Copper is reddish colored, takes on a bright metallic luster, and is malleable, ductile, and a good conductor of heat and electricity (second only to silver in electrical conductivity). The electrical industry is one of the greatest users of copper. Copper occasionally occurs native, and is found in many minerals such as cuprite, malachite, azurite, chalcopyrite, and bornite. Large copper ore deposits are found in the U.S., Chile, Zambia, Zaire, Peru, and Canada. The most important copper ores are the sulfides, oxides, and carbonates. From these, copper is obtained by smelting, leaching, and by electrolysis. Its alloys, brass and bronze, long used, are still very important; all American coins are now copper alloys; monel and gun metals also contain copper. The most important compounds are the oxide and the sulfate, blue vitriol; the latter has wide use as an agricultural poison and as an algicide in water purification. Copper compounds such as Fehling’s solution are widely used in analytical chemistry in tests for sugar. High-purity copper (99.999 + %) is readily available commercially. The price of commercial copper has fluctuated widely. The price of copper in December 2001 was about $1.50/kg. Natural copper contains two isotopes. Twenty-six other radioactive isotopes and isomers are known.

Verwenden

Copper-based ingredients are often used as coloring agents in cosmetics. Copper itself is nontoxic, but soluble copper salts, notably copper sulfite, are skin irritants. In the body, copper combines with certain proteins to produce a variety of enzymes, which in turn serve as catalysts for different functions. For example, copper plays a role in the keratinization process. In normal skin, this catalytic action is completed in 8 to 12 hours, however more than three days may be required in cases of copper deficiency. Through such enzymatic activity, copper is involved in melanin production, as decreased pigmentation has been observed in cases of copper deficiency. Such enzyme-based action also links copper to maintaining and repairing the skin’s connective tissues (collagen and elastin), as well as to wound healing.

Verwenden

Copper is a metal that occurs naturally throughout the environment, in rocks, soil, water, and air. Copper is an essential element in plants and animals (including humans), which means it is necessary for us to live. Therefore, plants and animals must absorb some copper from eating, drinking, and breathing.
The use of copper dates back to prehistoric times. The metal, its compounds, and alloys have numerous applications in every sphere of life–making it one of the most important metals. Practically all coinages in the world are made out of copper or its alloys. Its alloys, bronze and brass, date from ancient times. More modern alloys such as monel, gun metals, and berylliumcopper also have wide applications. The metal is an excellent conductor of electricity and heat and is used in electric wiring, switches and electrodes. Other applications are in plumbing, piping, roofing, cooking utensils, construction materials, and electroplated protective coatings. Its compounds, namely the oxides, sulfates, and chlorides, have numerous of commercial applications.
Copper is distributed widely in nature as sulfides, oxides, arsenides, arsenosulfides, and carbonates. It occurs in the minerals cuprite, chalcopyrite, azurite, chalcocite, malachite and bornite. Most copper minerals are sulfides or oxides. Native copper contains the metal in uncombined form.

Verwenden

manufacture of bronzes, brass, other copper alloys, electrical conductors, ammunition, copper salts, works of art.

Verwenden

Copper, being easy to mine and refine, has become a very versatile metal over the course ofcivilization. Early in human history, it was discovered that soft copper could be made harderand stronger when alloyed with other metals. Copper was and still is important to technologyand the development of civilizations. Over the past several thousand years, brass has foundmultiple uses, such as in coins, cooking utensils, and many types of instruments and hardwarethat are resistant to corrosion. Even today, brass is used to make musical instruments andbathroom, kitchen, and marine hardware. The U.S. one-cent penny was originally made ofcopper, but today the penny is made of zinc with a coating of copper. Copper is also an alloymetal used as a substitute for some of the silver in several other U.S. coins.Some common uses are in electrical wiring and components of electronic equipment,roofing, and pipes and plumbing and in the manufacturing of alloys such as brass, bronze,Monel metal, electroplating, jewelry, cooking utensils, insecticides, marine paints, cosmetics,and wood preservatives.Copper is second only to silver as an excellent conductor of electricity. This factor and itsavailability made it essential for the expansion of modern technologies. It was, and still is, adesired metal for wires to carry electricity, but the rapid expansion of modern communicationswould require more copper than could be made economically available. The solution has beento use optical fiberglass transmission cables as a substitute for copper wire. In addition, andeven more important, is the recent explosive growth of wireless transmission as a substitute forcopper wire in the communication industries.

Verwenden

Copper has been known since early times. Itis used to make utensils, electrical conductors,and alloys such as bronze, brass, andother copper alloys.

Verwenden

Copper is a metal necessary for the maintenance of normal erythro- poiesis and the prevention of iron deficiency anemia, iron being essential in hemoglobin synthesis.

Definition

Metallic element of atomic number 29, group IB of the periodic table, aw 63.546, valences 1, 2; two stable isotopes.

Vorbereitung Methode

Copper can be found free in nature (although not as commonly today). A naturally forming “patina” forms on copper in the environment (e.g., Statue of Liberty in NewYork City). The “patina” is commonly copper carbonate (from reaction with water and carbon dioxide). This thin copper carbonate layer covers exposed pure copper and prevents further oxidation. The name copper is derived from the Latin word cuprum, which, in turn, is derived from an earlier word, cyprium or “Cyprium metal.” The Romans obtained much of their copper from Cyprus, as the name implies.
Copper is found at a concentration of 50 ppm in the earth’s crust, and its concentration in seawater is 0.001–0.02 ppm. Although copper can also be obtained in an almost pure state in nature, about 85% of the copper mined today is derived from low-grade ores containing 2% or less of the metal. The major ore is chalcopyrite (CuFeS2). Ores are removed by open-pit mining as well as underground mining.

Allgemeine Beschreibung

Reddish lustrous malleable odorless metallic solid.

Air & Water Reaktionen

Solid pieces are very slowly oxidized by air to give a green basic carbonate. Solid pieces become covered by a black oxide when heated in air. Insoluble in water.

Reaktivität anzeigen

Copper combines violently with chlorine trifluoride in the presence of carbon [Mellor 2, Supp. 1, 1956]. Is oxidized by sodium peroxide with incandescence [Mellor 2:490-93, 1946-1947]. Forms an unstable acetylide when acetylene is passed over samples that have been heated enough to form an oxide coating. Reacts more rapidly in powdered or granular form. Subject to explosive reaction then mixed in finely divided form with finely divided bromates chlorates and iodates of barium, calcium, magnesium, potassium, sodium, or zinc; these reactions are initiated by heat, percussion, and occasionally light friction [Mellor 2:310, 1946-1947]. A solution of sodium azide in Copper pipe with lead joints formed Copper azide and lead azide, both of these compounds can detonate [Klotz, 1973].

Hazard

Flammable in finely divided form. Gastrointestinal irritant and metal fume fever.

Hazard

Copper dust and powder, as well as a few of its compounds, are flammable, or even explosivewhen ignited in contained areas. Many of copper’s compounds are extremely toxic andpoisonous either with skin contact or when inhaled or ingested and should be handled by professionals in controlled environments. Even so, both plants and animals, including humans,require traces of copper for the proper metabolism of their foods.

Health Hazard

The toxicity of metallic copper is very low.However, inhalation of its dusts, fumes, ormists or its salts can cause adverse healtheffects. Inhalation causes irritation of theeyes and mucous membranes, nasal perforation,cough, dry throat, muscle ache, chills,and metal fever. Skin contact can result indermatitis. Many copper(II) salts are toxic.

Health Hazard

Occupational workers exposed to copper fumes, dust and mists in work areas develop symptoms of poisoning. These include irritation to the mucous membrane, nasal, and pharyngeal irritation; nasal perforation, eye irritation, metallic or sweet taste, dermatitis; prolonged periods of exposure to high concentrations cause anemia, adverse effects to the lung, liver, and kidney. The exposed worker also suffers from metal fume fever; chills, muscle aches, nausea, fever, dry throat, coughing, weakness, lassitude, irritation of the eyes and the upper respiratory tract, discolored skin and hair, and acute lung damage. Occupational workers exposed to copper dust suffer from gastrointestinal disturbances, headache, vertigo, drowsiness, and hepatomegaly. Vineyard workers chronically exposed to Bordeaux mixture (copper sulfate and lime) exhibit degenerative changes of the lungs and liver. Dermal exposure to copper may cause contact dermatitis in some individuals. Copper is required for collagen formation. Copper defi ciency is associated with atherosclerosis and other cardiovascular conditions. Any kind of imbalance of copper in the body causes health disorders that include, but are not limited to, arthritis, fatigue, adrenal burnout, insomnia, scoliosis, osteoporosis, heart disease, cancer, migraine headaches, seizures, gum disease, tooth decay, skin and hair problems, and uterine fi broids, endometriosis (in females). Copper defi ciency is associated with aneurysms, gout, anemia, and osteoporosis. Exposures to copper in the form of dusts and mists cause irritation to the eyes, respiratory system, mucous membrane, nasal, pharyngeal irritation cough, dyspnea (breathing diffi culty), and wheezing. Prolonged exposures are known to cause nasal perforation. Copper has caused anemia and damage to the lung, liver, and kidney in experimental laboratory animals. Reports have indicated that copper dusts and fumes are potential occupational carcinogens.

Landwirtschaftliche Anwendung

Copper (Cu) is a transition element, belonging to Group 11 (formerly Group IA) of the Periodic Table. It is an important non-ferrous metal and a micronutrient with two distinct functions - to serve as a plant nutrient by being an activator or by being a part of certain enzymes like tyrosinase, lactase, ascorbic acid oxidase, cytochrome oxidase, etc., and secondly to play a role in many electron transfer processes. adsorbed
Copper is a component of several enzyme complexes that influence carbohydrate and nitrogen metabolism in plants. Its other function is to neutralize harmful soil conditions. This is done by adding copper sulphate to the soil to maximize the crop yield. The addition of large quantities of copper in certain peat soils in Kerala (India) was found to precipitate or inactivate some toxins present in the soil and neutralize the harmful conditions. About 70% of copper in a plant is found in chlorophyll and plays an important metabolic function.
Plants absorb copper through leaves as cupric ions (Cu2+)i n the form of a complex, such as EDTA. In soils, copper is found mostly in the cupric (Cu2+) form, adsorbed by clay minerals as well as organic complexes to an extent of 2 to 100ppm. The content of soil organic matter, pH and other metallic ions such as iron, manganese or aluminum influence the availability of copper in the soil. The amount of exchangeable copper decreases as the pH increases. Enhancing the concentration of aluminum beyond 0.1 ppm in soil solutions is found to decrease copper uptake in wheat plants. The ratio of copper to other metallic ions in the rooting medium is more important for plant growth than the absolute concentration of copper.
The retention of copper in soil increases in proportion to the organic matter content. Depending on their stability, copper-humus complexes make copper available to plants. The copper content in soil ranges from 5 to 60mg per kg, although both lower and higher values are not uncommon. The average amount of copper in soils is about 9 to 10mg per kg. The most familiar copper mineral in soils, chalcopyrite (CuFeS2), has copper in the cuprous (Cu+) form. These minerals have very low solubility which increases with pH. The nature of the reactions of copper with various organic matter is still to be fully explored. Soils which are high in organic matter are more prone to copper deficiencies than those with a lesser organic matter content.
The symptoms of copper deficiency vary with crops and are similar to those of potassium deficiency. Copper has low soil mobility and is considered to be deficient when the copper level is below 4 ppm in dry matter. Copper deficiency causes the early aging of chlorophyll and a subsequent fall in crop yield. Lucerne, carrot, onion, barley, oats, wheat and orange are sensitive to copper deficiency. Copper deficiency is common in vegetables, small grains and fruits growing on sands, organic soils or over-limed acidic soils. In corn, the youngest leaves become yellow and stunted. As the deficiency becomes severe, the young leaves turn pale and the older ones die In many vegetable crops, the leaves lack turgor and assume a bluish-green hue. Stem melanosis is a disease occuring in certain beet varieties due to copper deficiency. Organic soils are often copper deficient, as are calcareous soils, the pH of which falls in the range of 8.0to 8.4. A foliar spray of a few kilograms of copper salt per hectare is enough to correct copper deficiency for many years. Copper deficiency increases the incidence of lodging, when simultaneous growth occurs as a response to nitrogen fertilization. Since pollen and ovaries are very sensitive to copper deficiency, flowering and fruiting may be adversely affected or even become absent.
Like most micronutrients, excess copper is toxic to plants. It reduces the iron activity and leads to iron deficiency.
Copper toxicity symptoms include a reduc

Industrielle Verwendung

The most important characteristics of copperimmersion coatings are their high electricalconductivity, good lubrication properties, andunique appearance. In addition to steel, they canbe applied to brass and aluminum and to printedcircuit boards.
Because of their conductivity, copper immersioncoatings have proved particularly usefulfor printed circuits. They are not especiallynoted for their decorative appeal, but can beused in applications where a particular appearanceis required, e.g., inexpensive, decorativehardware such as casket parts.
