· JVASP-92705· KFe2S2

KFe₂S₂ is an iron sulfide compound with potassium, belonging to the family of metal sulfides that exhibit metallic character and moderate structural rigidity. This material has been investigated primarily in materials research and solid-state chemistry contexts rather than as an established commercial product, with potential applications in thermoelectric devices, battery electrodes, and catalytic systems where sulfide compounds show promise for energy conversion and storage.

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.
