· JVASP-96925· Fe7S8

Fe7S8 is an iron sulfide compound belonging to the family of transition metal sulfides, representing a mixed-valence iron sulfide phase with potential applications in energy storage and catalysis research. This material is primarily of academic and emerging industrial interest rather than an established commodity material, studied for its electrochemical properties in battery systems and as a catalyst precursor for hydrogen evolution and other reactions. Its notable characteristic among iron sulfides is the specific iron-to-sulfur ratio, which influences its electrical conductivity and redox activity compared to common phases like FeS and FeS2.

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.
