Fe3S4
metal· JVASP-86963· Fe3S4
Fe₃S₄ is an iron sulfide compound that exists as a mixed-valence ferrous-ferric sulfide, representing an intermediate phase in the iron-sulfur system. While not widely used as a primary engineering material in current industrial practice, Fe₃S₄ is primarily encountered in corrosion science, pyrometallurgy, and materials research contexts where it forms as a corrosion product on steel in sulfurous environments or as a phase in roasted sulfide ore processing. Engineers may encounter this compound when analyzing failure mechanisms in high-temperature sulfidation, designing corrosion-resistant alloys for sour gas applications, or studying iron sulfide phase chemistry in mineral processing operations.

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.
