· JVASP-101230· Bi4Te3S3

Bi₄Te₃S₃ is a mixed chalcogenide ceramic compound combining bismuth, tellurium, and sulfur—a hybrid member of the bismuth chalcogenide family that bridges traditional thermoelectric and semiconductor material platforms. This is a research-phase compound studied primarily for thermoelectric applications where the blended chalcogenide structure offers potential for tuning electrical and thermal transport properties; while bismuth telluride (Bi₂Te₃) dominates commercial thermoelectric devices, mixed-anion variants like this are explored to optimize figure-of-merit (ZT) or enable new processing routes.

Regulatory Screening

Environmental

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.
