BISMUTH TELLURIDE(Cas 1304-82-1) Usage
|
Reactivity Profile |
BISMUTH TELLURIDE may emit toxic fumes of tellurium when heated to decomposition. Incompatible with strong oxidizing agents such as nitric acid or bromine, chlorine or fluorine. Moderate fire hazard by reaction with such materials. May react with strong acids to evolve toxic gases; may react slowly with water to evolve toxic gases. Slight explosion hazard with moisture. |
|
Hazard |
Toxic. |
|
Health Hazard |
Bismuth telluride, either alone or doped with selenium sulfide, is apparently of very low toxicity. In limited industrial experimental work with bismuth telluride under controlled conditions (vacuum hoods), no adverse health effects were encountered other than tellurium breath. |
|
Potential Exposure |
Bismuth telluride is used in thermoelectric cooling, power generation, semiconductor manufacture; pharmaceuticals; medical therapy; cosmetics. Exposure involves those working in “Silicon Valley” and similar locations around the world. An alloy of two metallic elements that are sometimes doped with SeS. The SeS dopant alters the electrical properties, but has too low a concentration to affect the chemical properties. |

Shipping |
UN3284 Tellurium compound, n.o.s., Hazard Class: 6.1; Labels: 6.1—Poisonous materials, Technical Name Required. |
|
Incompatibilities |
Reacts with acids forming toxic gases. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Toxic and flammable gas may slowly evolve from contact with moisture. |
