Application
Bismuth telluride serves a critical purpose in the development of thermoelectric devices, particularly those operating at room temperature, due to its exceptional properties as a semiconductor. This gray crystalline solid is renowned for its ability to convert temperature differences directly into electrical voltage and vice versa, making it a key material in achieving significant thermoelectric efficiency, with ZT values reaching up to 2.4. Its unique characteristics, such as a specific gravity of 7.7 and a melting point of 573°C, along with its safety profile-rated as moderately hazardous in terms of health, flammability, and reactivity-underscore its utility and practicality in advanced material science applications. Although insoluble in water, bismuth telluride's utility is enhanced through doped variations, often containing additional compounds like stannous telluride, to optimize performance for commercial thermoelectric systems.
