Antimony Usage And Synthesis
DescriptionAntimony occurs in nature primarily in the mineral stibnite, and also in several other ores, such as valentinite, senarmontite, cervantite, kermasite, livingstonite, and jamisonite. It is also found in lead scraps from batteries.
Antimony alloys have many commercial applications. The metal makes its alloys hard and stiff and imparts resistance to corrosion. Such alloys are used in battery grids and parts, tank linings, pipes and pumps. The lead plates in the lead storage batteries constitute 94% lead and 6% antimony. Babbit metal, an alloy of antimony, tin, and copper is used to make antifriction machine bearings. Alloys made from very high purity grade antimony with indium, gallium and bismuth are used as infrared detectors, diodes, hall effect devices and thermoelectric coolers.
Production MethodsAntimony is obtained from its ores, stibnite, Sb2S3 or tetrahedrite, 3Cu2S . Sb2S3. The metal is recovered from high-grade stibnite by reduction with iron:
Sb2S3 + 3 Fe → 2 Sb + 3 FeS
Alternatively, low-grade stibnite ore is converted to its oxide which is then reduced with carbon. Tetrahedrite may be treated with sodium sulfide solution. The solution containing thioantimonate formed is then electrolyzed in a diaphragm cell using a steel cathode and lead anode. The metal is further refined by oxidation or electrorefining process.
Sb may be made in the laboratory by reduction of antimony pentoxide with potassium cyanide.
Chemical PropertiesAntimony 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.
Chemical PropertiesAntimony is a silvery-white, lustrous, hard, brittle metal; scale-like crystals, or dark gray lustrous powder
Chemical Propertiesgrey powder
HistoryAntimony 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%).
UsesIn 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.
General DescriptionA 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.
Reactivity ProfileANTIMONY 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].
HazardUse with adequate ventilation. Soluble salts are toxic.
Health HazardOxides from metallic fires are a severe health hazard. Inhalation or contact with substance or decomposition products may cause severe injury or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.
Health HazardThe toxicity of antimony compounds is comparable to that of arsenic, but as antimony compounds are hardly absorbed in the gastrointestinal tract, there is less hazard of acute poisoning. In addition, antimony compounds often cause vomiting, thus being removed from the organism. Chronic poisoning may result in damage to the liver, kidneys, and even the heart and the circulatory system. The symptoms differ among the compounds. Stibine accumulates in fatty tissue. Exposures to antimony and its compounds cause poisoning and toxicity to the worker with symptoms that include, but are not limited to, irritation to eyes, skin, nose, and throat, ulceration of nasal septum and larynx, dermatitis as characterized by antimony spots, cough, dizziness, seizures, headache, anorexia, nausea, vomiting, diarrhea, stomach cramps, bloody stools, insomnia, inability to smell properly, metallic taste, cardiovascular disturbances, pulmonary edema, pharyngitis, tracheitis, heart and lung damage, pneumoconiosis, slow and shallow respiration, coma, and death. Antimony fumes and dusts inhaled by occupational workers are associated with the development of benign tumors of the lungs, dermatitis and, less commonly, effects on the heart and kidneys. Laboratory animals exposed to antimony by inhalation or ingestion exhibit effects similar to those noted in humans. Antimony can be measured in the urine, feces, and blood. To date, little is known about the environmental risks involved. Water pollution seldom occurs because of the low solubility of most compounds. Extreme caution should be taken when coming into direct contact with antimony compounds.
Fire HazardMay 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.
Safety ProfileAn 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.
Potential ExposureExposure 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.

ShippingUN2871 Antimony powder, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
IncompatibilitiesPyrophoric. 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.
Waste DisposalRecovery 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.
PrecautionsAntimony 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.
