· JVASP-144678· CuBi5S8

CuBi5S8 is a ternary copper-bismuth sulfide compound that belongs to the metal sulfide family, combining metallic copper and bismuth with sulfur in a fixed stoichiometric ratio. This material is primarily of research and development interest for thermoelectric applications and energy conversion systems, where mixed-metal sulfides are being explored as alternatives to traditional thermoelectric materials due to their potential for tunable electronic and thermal properties. Its industrial adoption remains limited, but the copper-bismuth-sulfide system represents a promising research direction for applications requiring moderate-temperature heat-to-electricity conversion where cost-effectiveness and scalability may offer advantages over conventional materials.

Export Control

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.
