ceramic· JVASP-101468· Bi2Sb2Te3Se3
Bi2Sb2Te3Se3 is a quaternary chalcogenide compound belonging to the thermoelectric material family, combining bismuth, antimony, tellurium, and selenium in a layered crystal structure. This material is primarily investigated in thermoelectric cooling and power generation applications, where its tuned bandgap and carrier concentration offer improved performance over traditional binary compounds like Bi2Te3. The mixed composition enables fine control of the Seebeck coefficient and electrical conductivity, making it relevant for researchers optimizing thermal-to-electric conversion efficiency in mid-temperature ranges.

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.
