· Sr3 Bi1 Sb1

Sr3Bi1Sb1 is an experimental intermetallic semiconductor compound combining strontium, bismuth, and antimony in a fixed stoichiometric ratio. This material belongs to the family of bismuth-antimony-based semiconductors, which are primarily of research interest for thermoelectric and optoelectronic applications where the layered crystal structure and narrow bandgap characteristics of bismuth-antimony compounds are leveraged. The material is not yet established in mainstream commercial production, but compounds in this family are investigated for potential use in low-temperature thermoelectric devices, infrared detectors, and specialized semiconductor applications where bismuth-antimony alloys show promise over conventional alternatives.

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.
