개요

Antimony (Sb) has been known since antiquity, and its early use as a cosmetic continues even today. Often mixed with lead or other heavy metals, this mascara-type cosmetic is known as kohl. Believed to possess powers to shield the eye from the sun and disease, it served purposes in both cosmetics and mysticism. Antimony has been found in many artifacts in the Middle East, and seems to have been used in the creation of small personal ornamentation or vessels.

화학적 성질

Antimony is a silvery-white metal found in the earth’s crust. It is insoluble in hot or cold water, but soluble in hot concentrated sulfuric acid and hot nitric acid, and reacts with oxidizing acids and halogens (fl uorine, chlorine, or bromine). It does not react with water at room temperature, but will ignite and burn in air at higher temperatures. Ores of antimony are mined and later mixed with other metals to form antimony alloys, which are used in lead storage batteries, solder, sheet and pipe metal, bearings, castings, and pewter. Antimony oxide is added to textiles and plastics to prevent them from catching fi re. It is also used in paints, ceramics, and fi reworks, and as enamels for plastics, metal, and glass. Antimony is alloyed with other metals, such as lead, to increase its hardness and strength; its primary use is in antimonial lead, which is used in grid metal for lead acid storage batteries. Antimony salts are used in the treatment of leishmaniasis and schistosomiasis.

화학적 성질

Antimony is a silvery-white, lustrous, hard, brittle metal; scale-like crystals, or dark gray lustrous powder

물리적 성질

Physically, antimony’s properties are related to sulfur and some of the nonmetals, butchemically, its properties are related to metals. It behaves like a metal and is often found innature along with other metals. In its pure form it is rather hard and brittle with a grayishcrystal structure.

Isotopes

There are 53 isotopes of antimony. They range from Sb-103 to Sb-139 (a fewhave two forms). Their half-lives range from 150 nanoseconds to 2.7 years. The twostable isotopes of antimony and their contribution to the natural abundance of antimonyon Earth are as follows: Sb-121 = 57.21% and Sb-123 = 42.79%.

Origin of Name

The element’s name comes from the Greek words anti and minos, which mean “not alone,” and antimony’s symbol (Sb) is derived from the name for its ancient source mineral, stibnium.

출처

Although antimony is not a rare metal, it is not well known, despite having been knownand used for many centuries. It is the 63rd most abundant element on Earth, and it occursmainly as sulfide ores or in combination with the ores of other metals. The ore that is theprimary source of antimony is the mineral stibnite (antimony sulfide, Sb2S3). Antimony is alsofound in copper, silver, and lead ores. Breithauptite (NiSb) and ullmanite (NiSbS) are twoores containing nickel. Dicrasite (Ag2Sb) and pyrargyrite (Ag3SbS3) are silver ores containingsome antimony.

Characteristics

There are two allotropes of antimony. The native metallic form is one allotrope, and theother allotrope is an amorphous grayish form. Antimony is a true metalloid that is brittle witha low melting point. And similar to nonmetals, it is a poor conductor of heat and electricity.
Antimony is unique in that when it solidifies from a molten liquid state to a solid state, itexpands, which is just the opposite of most metals. This is useful in making some typesettingcastings in which the expansion assures an accurate reproduction of the letter mold.

역사

Antimony was recognized in compounds by the ancients and was known as a metal at the beginning of the 17th century and possibly much earlier. It is not abundant, but is found in over 100 mineral species. It is sometimes found native, but more frequently as the sulfide, stibnite (Sb2S3); it is also found as antimonides of the heavy metals, and as oxides. It is extracted from the sulfide by roasting to the oxide, which is reduced by salt and scrap iron; from its oxides it is also prepared by reduction with carbon. Two allotropic forms of antimony exist: the normal stable, metallic form, and the amorphous gray form. The so-called explosive antimony is an ill-defined material always containing an appreciable amount of halogen; therefore, it no longer warrants consideration as a separate allotrope. The yellow form, obtained by oxidation of stibine, SbH3, is probably impure, and is not a distinct form. Natural antimony is made of two stable isotopes, 121Sb and 123Sb. Forty-five other radioactive isotopes and isomers are now recognized. Metallic antimony is an extremely brittle metal of a flaky, crystalline texture. It is bluish white and has a metallic luster. It is not acted on by air at room temperature, but burns brilliantly when heated with the formation of white fumes of Sb203. It is a poor conductor of heat and electricity, and has a hardness of 3 to 3.5. Antimony, available commercially with a purity of 99.999 + %, is finding use in semiconductor technology for making infrared detectors, diodes, and Hall-effect devices. Commercial-grade antimony is widely used in alloys with percentages ranging from 1 to 20. It greatly increases the hardness and mechanical strength of lead. Batteries, antifriction alloys, type metal, small arms and tracer bullets, cable sheathing, and minor products use about half the metal produced. Compounds taking up the other half are oxides, sulfides, sodium antimonate, and antimony trichloride. These are used in manufacturing flame-proofing compounds, paints, ceramic enamels, glass, and pottery. Tartar emetic (hydrated potassium antimonyl tartrate) has been used in medicine. Antimony and many of its compounds are toxic. Antimony costs about $1.30/kg for the commercial metal or about $12/g (99.999%).

용도

In manufacture of alloys, such as Britannia or Babbitt metal, hard lead, white metal, type, bullets and bearing metal; in fireworks; for thermoelectric piles, blackening iron, coating metals, etc.

용도

Antimony is used to make alloys such asBabbit metal, white metal, and hard lead; inbullets and fireworks; and for coating metals.
Also, it is used in lead storage batteries,solder bearings, castings and pewter. Antimonyoxide has numerous applications. It isused in paints, ceramics and fireworks andis added to textiles. The average concentrationof antimony in the urban air in USA isestimates as 0.001μg/m3.

용도

Today the most common use of antimony is as an alloy metal with lead to make the leadharder. This lead–antimony alloy is used for electrical storage batteries, for sheathing for electricaland TV cables, in the making of wheel bearings, and as solder.
Although it is a brittle metal, it has found a use in the semiconductor industry in theproduction of diodes and infrared devices. It is also used to flameproof material and vulcanizerubber and can also be a component in paints, ceramic enamels, glass, pottery, andfireworks.
Antimony has few other uses except as an alloy to harden other materials. One recentdevelopment was to add antimony oxide to polyvinyl chloride (PVC pipe) to act as a flameretardant.

Antimony has several allotropes.The stable form is a bluishwhitemetal. Yellow antimony andblack antimony are unstable nonmetallicallotropes made at low temperatures.The main source isstibnite (Sb2S3), from which antimonyis extracted by reduction withiron metal or by roasting (to give theoxide) followed by reduction withcarbon and sodium carbonate. Themain use of the metal is as an alloyingagent in lead-accumulator plates,type metals, bearing alloys, solders,Britannia metal, and pewter. It is alsoan agent for producing pearlitic castiron. Its compounds are used inflame-proofing, paints, ceramics,enamels, glass dyestuffs, and rubbertechnology. The element will burn inair but is unaffected by water or diluteacids. It is attacked by oxidizingacids and by halogens. It was first reportedby Tholden in 1450.

일반 설명

A silvery or gray solid in the form of dust. Denser than water and insoluble in water. Toxic by inhalation and by ingestion. May burn and emit toxic fumes if heated or exposed to flames. Used to make electric storage batteries and semiconductors.

반응 프로필

ANTIMONY is spontaneously flammable in fluorine, chlorine, and bromine. With iodine, the reaction produces heat, which can cause flame or even an explosion if the quantities are great enough [Mellor 9:379 1946-47]. Even at 10° C. bromine trifluoride reacts with antimony incandescently. Bromine trifluoride reacts similarly with arsenic, boron, bromine, iodine, phosphorus, and sulfur [Mellor 2:113 1946-47]. Bromoazide explodes on contact with antimony, arsenic, phosphorus, silver foil, or sodium. Antimony is very shock sensitive. Explosions of chloric acid have been due to the formation of unstable compounds with antimony, bismuth, ammonia, and organic matter [Chem. Abst. 46:2805e 1952]. The reaction of finely divided antimony and nitric acid can be violent [Pascal 10:504 1931-34]. Powdered antimony mixed with potassium nitrate explodes when heated [Mellor 9:282 1946-47]. When antimony or arsenic and solid potassium permanganate are ground together, the metals ignite [Mellor 12:322 1946-47]. Sodium peroxide oxidizes antimony, arsenic, copper, potassium, tin, and zinc with incandescence [Mellor 2:490-93 1946-47].

위험도

The powder and dust of antimony are toxic and can cause damage to the lungs. The fumesof antimony halogens (chlorides and fluorides) are especially dangerous when inhaled or incontact the skin.
Many of the salts of antimony are carcinogenic and can cause lung cancer if inhaled, as wellas other cancers if ingested. This is a major hazard with the radioisotopes of antimony used inindustry. Some of its sulfide compounds are explosive.

건강위험

The toxicity of antimony is of low order,much less poisonous than arsenic. The symptoms of acute poisoning include weightloss, loss of hair, eosinophilia, and congestionof heart, liver, and kidney. GI disorder(vomiting and diarrhea) and respiratory distressmay arise from high doses. Chronic oralexposure may cause disorder in blood andliver. The toxic routes are primarily inhalationof its dusts or fumes, skin absorption oringestion of contaminated food.

화재위험

May react violently or explosively on contact with water. Some are transported in flammable liquids. May be ignited by friction, heat, sparks or flames. Some of these materials will burn with intense heat. Dusts or fumes may form explosive mixtures in air. Containers may explode when heated. May re-ignite after fire is extinguished.

Pharmaceutical Applications

Antimony presents itself in a metallic grey form. Antimony is obtained from stibnite (Sb2S3) after reduction with iron.

공업 용도

Antimony is a bluish-white metal, symbol Sb,with a crystalline scalelike structure that exhibitspoor electrical and heat conductivity. It isbrittle and easily reduced to powder. It is neithermalleable nor ductile and is used only in alloysor in its chemical compounds. Like arsenic andbismuth, it is sometimes referred to as a metalloid,but in mineralogy it is called a semimetal.The element is available commercially in99.999+% purity and is finding increasing usein semiconductor technology.
Antimony is produced either by roasting thesulfide with iron, or by roasting the sulfide andreducing the sublimate of Sb4O6 thus producedwith carbon; high-purity antimony is producedby electrolytic refining. Antimony is one of thefew elements that exhibits the unique propertyof expanding on solidification. Antimony isordinarily stable and not readily attacked by airor moisture. Under controlled conditions it willreact with O2 to form oxides. The chief uses ofantimony are in alloys, particularly for hardeninglead-base alloys.
Antimony imparts hardness and a smoothsurface to soft-metal alloys, and alloys containingantimony expand on cooling, thus reproducingthe fine details of the mold. This propertymakes it valuable for type metals. When alloyedwith lead, tin, and copper, it forms the babbittmetals used for machinery bearings. It is alsomuch used in white alloys for pewter utensils.Its compounds are used widely for pigments.

Safety Profile

An experimental poison by intraperitoneal route. Questionable carcinogen with experimental carcinogenic data. Moderate fire and explosion hazard in the forms of dust and vapor when exposed to heat or flame. See also POWDERED METALS. When heated or on contact with acid it emits toxic fumes of SbH3. Electrolysis of acid sulfides and stirred Sb halide yields explosive Sb. It can react violently with NH4NO3, halogens, BrN3, BrF3, HClO3, Cl0, ClF3, HNO3, m03, KMn04, K2O2, NaNO3, oxidants.

잠재적 노출

Exposure to antimony may occur during mining, smelting or refining; alloy and abrasive manufacture; and typesetting in printing. Antimony is widely used in the production of alloys, imparting increased hardness, mechanical strength, corrosion resistance, and a low coefficient of friction. Some of the important alloys are Babbitt, pewter, white metal, Britannia metal and bearing metal (which are used in bearing shells), printing-type, metal, storage battery plates, cable sheathing, solder, ornamental castings, and ammunition. Pure antimony compounds are used as abrasives, pigments, flame-proofing compounds, plasticizers, and catalysts in organic synthesis; they are also used in the manufacture of tartar emetic, paints, lacquers, glass, pottery, enamels, glazes, pharmaceuticals, pyrotechnics, matches, and explosives. In addition, they are used in dyeing, for blueing steel; and in coloring aluminum pewter; and zinc. A highly toxic gas, stibine, may be released from the metal under certain conditions.

Carcinogenicity

Existing experimental data suggest that antimony may be an animal carcinogen, but there is lack of data on the possible carcinogenic properties of antimony and antimony compounds for human exposures. The ACGIH refers to unpublished data on a large antimony smelter in the United Kingdom in the 1960s where workers were exposed to antimony trioxide ranging from 0.5 to 40mg/m3. The data may indicate increased mortality in lung cancer among the heavily exposed workers, but the workers were also exposed to zirconium making the data cited dif?cult to interpret.

환경귀착

The toxicity of Sb is a function of the water solubility and the oxidation state of the Sb species under consideration. Antimony( III) is generallymore toxic than antimony(V) and inorganic forms are thought to be more toxic than organic forms. Stibane gas (SbH3) when inhaled is the most toxic. Antimony toxicity often parallels that of arsenic, although antimony salts are less readily absorbed than arsenic. It is presumed that antimony, like arsenic, complexes with sulfhydryl groups of essential enzymes and other proteins. By analogy, antimony can uncouple oxidative phosphorylation, which would inhibit the production of energy necessary for cellular functions. Antimony’s trivalent compounds are more toxic than its pentavalent compounds.

Toxicity evaluation

Antimony is found naturally in the Earth’s crust and can be released into the environment as windblown dust or sea spray or from volcanic eruptions or forest fires. However, the emission of antimony into the environment is overwhelmingly the result of human activity, with the emission of antimony trioxide, tetroxide, and pentoxide forms being the most significant. Antimony trioxide is emitted as a result of coal burning, or with fly ash when antimony-containing ores are smelted. Humans are exposed to low amounts of antimony from the air, drinking water, and food contaminated with soil. Antimony concentration in the atmosphere is thought to be 1.4–55 ng m-3. The more water soluble forms of antimony are very mobile in aqueous media while the less soluble forms of antimony are found attached to particles of soil, clay, and sediment in rivers and lakes. The concentration of antimony in the Pacific Ocean was found to be 0.2 mg l-1 and in the Rhine river at 0.1 μg l-1. The trivalent state of antimony is the form most often released by anthropogenic activities. In terms of soil concentrations, it was reported by a US Geological Survey to be less than 1–8 ppm in soil, with an average of 0.48 ppm. Studies have estimated an exposure of less than 5 mg day1 on average from food and water and appears to be significantly higher than exposure by inhalation.

비 호환성

Pyrophoric. Finely dispersed powder may form explosive mixture in air. Strong oxidizers; strong acids , produce a violent reaction, and deadly stibine gas (antimony hydride). Heat forms stibine gas. Mixtures with nitrates or halogenated compounds may cause combustion. Forms an explosive mixture with chloric and perchloric acid. Note: Stibine is formed when antimony is exposed to nascent (freshly formed) hydrogen.

폐기물 처리

Recovery and recycling is an option to disposal which should be considered for scrap antimony and spent catalysts containing antimony. Dissolve spilled material in minimum amount of concentrated HCl. Add water, until white precipitate appears. Then acidify to dissolve again. Saturate with H2S. Filter, wash and dry the precipitate and return to supplier. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.

주의 사항

Antimony trioxide is incompatible with bromine trifl uoride, strong acids, strong bases, reducing agents, perchloric acid, and chlorinated rubber. The release of the deadly gas, stibine, and its inhalation cause adverse effects on the respiratory, gastrointestinal, and cardiovascular systems. Workers must wear impervious protective clothing, including boots, gloves, laboratory coat, apron or coveralls, as appropriate, to prevent skin contact.
