general description grayish-white, lustrous, brittle, crystalline solid; dark-gray to brown, amorphous powder with metallic characteristics. used as a coloring agent in chinaware, porcelains, enamels, glass; producing black finish on silverware; semiconductor devices and research; manufacturing special alloys of marked electrical resistance. improves mechanical properties of lead; powerful carbide stabilizer in cast iron, tellurium vapor in "daylight" lamps, vulcanization of rubber. blasting caps. semiconductor research.
air & water reactions a finely divided suspension of elemental tellurium in air will explode. insoluble in water.
reactivity profile tellurium is attacked by chlorine fluoride with incandescence. when tellurium and potassium are warmed in an atmosphere of hydrogen, combination occurs with incandescence [mellor 11:40. 1946-47]. burning tellurium produces toxic tellurium oxide gas. avoid solid sodium, halogens, interhalogens, metals, hexalithium disilicide. reacts with nitric acid; reacts with concentrated sulfuric acid forming a red solution. dissolves in potassium hydroxide in the presence of air with formation of deep red solution; combines with halogens. avoid antimony and chlorine trifluoride; chlorine trifluoride reacts vigorously with tellurium producing flame. fluorine and tellurium react with incandescence. lithium silicide attacks tellurium with incandescence. reaction with zinc is accompanied by incandescence (same potential with cadmium, only hazard is less). a vigorous reaction results when liquid tellurium is poured over solid sodium [epa, 1998].
health hazard causes central nervous system depression. moderate skin and eye irritant. tellurium is capable of doing harm within the body by replacing the essential element sulfur.
fire hazard a finely divided suspension of elemental tellurium in air will explode. burning tellurium produces toxic tellurium oxide gas. avoid solid sodium, halogens, interhalogens, metals, hexalithium disilicide. reacts with nitric acid; reacts with concentrated sulfuric acid forming a red solution. dissolves in potassium hydroxide in the presence of air with formation of deep red solution; combines with halogens. avoid antimony and chlorine trifluoride; chlorine trifluoride reacts vigorously with tellurium producing flame. fluorine and tellurium react with incandescence. lithium silicide attacks tellurium with incandescence. reaction with zinc is accompanied by incandescence (same potential with cadmium, only hazard is less). a vigorous reaction results when liquid tellurium is poured over solid sodium.
