Fe3 S4
metal· Fe3 S4
Fe₃S₄ is an iron sulfide compound that exists as a mixed-valence iron sulfide phase, structurally related to the troilite (FeS) and pyrite (FeS₂) families. It is primarily encountered in research contexts and high-temperature industrial processes rather than as a primary engineering material, with applications emerging in energy storage, catalysis, and corrosion studies where its sulfide chemistry and iron content are leveraged.

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.
