BISMUTH TELLURIDE Usage And Synthesis

Uses Bi2Te3, along with Sb2Te3 and other structurally analogous semiconductors, is widely regarded as one of the best materials for room-temperature thermoelectric devices. Bismuth(III) telluride is a key component of thermoelectric materials that have reached ZT values as high as 2.4 at room temperature.

General Description Gray or black hexagonal platelets with a metallic luster or gray powder. Mp: 586°C. Density: 7.8 g cm-3. An alloy of two metallic elements.

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.
