· Bi0.4Sb1.6Te3

Bi0.4Sb1.6Te3 is a bismuth–antimony–telluride solid solution, a p-type thermoelectric compound engineered by tuning the bismuth-to-antimony ratio within the well-established Bi₂Te₃–Sb₂Te₃ system. This material is designed for mid-range thermoelectric cooling and power generation applications, where the modified composition optimizes the trade-off between electrical conductivity and thermal conductivity compared to pure binary compounds. Engineers select this alloy when device performance, cost, or thermal operating windows demand better figure-of-merit than legacy Bi₂Te₃, making it relevant for Peltier coolers, waste-heat recovery systems, and temperature-stabilized optical or sensor packages.

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.
