· Bi0.4Te3Sb1.6

Bi0.4Te3Sb1.6 is a quaternary compound within the bismuth telluride–antimony telluride family, engineered as a solid-solution thermoelectric material. This composition represents an experimental optimization of the Bi–Te–Sb ternary system, where substitution of bismuth with antimony modulates the electronic structure and phonon scattering to enhance thermoelectric performance. The material is investigated primarily in research and development contexts for mid-temperature thermoelectric applications where improved figure-of-merit (ZT) and thermal stability are sought compared to parent binary or simpler ternary phases.

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.
