· JVASP-123845· Bi5Sb

Bi5Sb is a bismuth-antimony intermetallic compound classified as a ceramic material, representing a member of the Group V semimetal alloy family. This material is primarily of research and specialized industrial interest for thermoelectric applications, where bismuth-antimony compounds are valued for their ability to convert thermal gradients into electrical current or vice versa. The material is notable in low-temperature thermoelectric cooling and power generation contexts, where it competes with more established bismuth telluride-based systems but offers potential advantages in cost or environmental profile; however, applications remain largely confined to niche cooling devices and advanced research rather than mainstream engineering use.

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.
