Bismuth telluride - Wikipedia

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.Bismuth Telluride (Bi2Te3) SemiconductorsBismuth telluride is a compound of tellurium and bismuth. When alloyed with selenium or antimony, it acts as an efficient thermoelectric material suitable for portable power generation or refrigeration. It is a narrow gap layered semiconductor with a trigonal unit cell. It mainly occurs in a rare mineral tellurobismuthite.Bismuth Telluride - Thermoelectric GeneratorBismuth Telluride A thermoelectric semiconductor material that exhibits optimum performance in a room temperature range.
