· Bi0.6Sb1.4Te3

Bi₀.₆Sb₁.₄Te₃ is a bismuth-antimony telluride compound and a member of the thermoelectric semiconductor family, engineered to optimize the Seebeck effect for direct thermal-to-electrical energy conversion. This material is used in thermoelectric cooling devices and power generation applications where small temperature differentials need to be converted to electricity or controlled precisely. It is notable for offering improved thermoelectric performance compared to pure bismuth telluride through compositional tuning of the bismuth-to-antimony ratio, making it relevant for waste heat recovery systems, spacecraft thermal management, and solid-state refrigeration where reliability and long operational life are priorities over maximum power density.

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.
