· JVASP-56776· BiTe

Bismuth telluride (BiTe) is a narrow-bandgap semiconductor ceramic compound belonging to the V–VI chalcogenide family, primarily studied for its thermoelectric properties. It is widely used in thermoelectric cooling modules, power generation from waste heat, and temperature sensing applications where conversion between thermal and electrical energy is required. BiTe is notable for its relatively high figure-of-merit in the mid-temperature range compared to many alternatives, making it the material of choice for commercial thermoelectric devices despite competing compounds like lead telluride and skutterudites.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
