· JVASP-59907· CaFe2S4

CaFe2S4 is a calcium iron sulfide compound belonging to the thiospinel family of materials, characterized by mixed-valence iron cations in a sulfide lattice. This compound is primarily investigated in materials research for its potential in energy storage and catalytic applications, particularly as a cathode material for alternative battery chemistries and as a precursor for iron sulfide-based catalysts. The material offers interest over conventional oxides in electrochemical and sulfide-based systems where the sulfide anion framework can provide enhanced ionic transport or catalytic sites.

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.
