· JVASP-101731· CrFeSb4

CrFeSb4 is an intermetallic compound combining chromium, iron, and antimony in a 1:1:4 stoichiometric ratio. This material belongs to the family of ternary transition metal antimonides, which are primarily investigated as thermoelectric materials and semiconductors for temperature-dependent electrical and thermal applications. While not yet widely deployed in high-volume production, CrFeSb4 and related antimonide compounds show promise for next-generation thermoelectric devices where efficient heat-to-electricity conversion or precise thermal management is required.

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.
