· Bi1.4Te3Sb0.6

Bi1.4Te3Sb0.6 is a bismuth telluride-antimony compound semiconductor belonging to the chalcogenide family, engineered for thermoelectric applications through compositional doping of the base Bi2Te3 system. This material is investigated primarily in research and emerging commercial contexts for solid-state heat conversion, where the bismuth and antimony ratio is optimized to enhance figure-of-merit and operating temperature range compared to unmodified Bi2Te3. The substitution of antimony into the telluride matrix targets improved performance in mid-range temperature thermoelectric devices, making it relevant for waste heat recovery, refrigeration, and specialized thermal management systems where conventional cooling or heating is inefficient.

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.
