· JVASP-29442· Bi14Te13S8

Bi14Te13S8 is a mixed-chalcogenide ceramic compound combining bismuth, tellurium, and sulfur elements, representing an emerging material in the thermoelectric and layered-structure ceramics family. This is primarily a research-phase material being investigated for thermoelectric applications and energy conversion systems, where the combination of elements and layered crystal structure offers potential for enhanced phonon scattering and reduced thermal conductivity compared to conventional thermoelectric materials. The bismuth telluride sulfide system is notable for its tunable electronic and thermal properties through compositional engineering, making it a candidate for next-generation solid-state cooling and waste-heat recovery devices, though industrial deployment remains limited.

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.
