Bismuth telluride (Bi₂Te₃)(CAT: M047738) is a gray, crystalline compound and a leading thermoelectric material known for its ability to directly convert heat into electricity and vice versa. It crystallizes in a layered rhombohedral structure, enabling high electrical conductivity and low thermal conductivity—properties that maximize thermoelectric efficiency. Widely used in power generation from waste heat and in solid-state cooling devices, Bi₂Te₃ is particularly effective near room temperature. It also exhibits topological insulator properties, making it of interest in advanced electronics and quantum computing research. Stable under normal conditions, it requires careful handling to avoid tellurium-related toxicity during processing.
