· Cr1 Fe2 Sb1

Cr₁Fe₂Sb₁ is an intermetallic semiconductor compound combining chromium, iron, and antimony in a 1:2:1 stoichiometric ratio. This material belongs to the family of ternary Heusler or half-Heusler compounds, which are actively researched for thermoelectric and spintronic applications due to their tunable electronic structure and potential for efficient energy conversion. While not yet widely commercialized, Cr-Fe-Sb compounds are of interest to materials researchers exploring alternatives to bismuth telluride thermoelectrics and as candidates for magnetic semiconductor devices where ferromagnetism and carrier transport can be engineered simultaneously.

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.
