· Bi1.4Sb0.6Te3

Bi1.4Sb0.6Te3 is a bismuth-antimony-telluride compound semiconductor belonging to the thermoelectric material family, engineered through doping and composition tuning to optimize the figure of merit (ZT) for thermal energy conversion. This p-type composition is widely studied and commercially deployed in thermoelectric cooling modules and waste heat recovery systems, where it outperforms simpler binary tellurides by offering improved electrical conductivity and thermal properties at moderate temperatures (200–400 K). Engineers select this alloy composition when conventional refrigeration is impractical, when compact solid-state cooling is required, or when recovering waste heat from industrial processes and power generation systems.

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.
