Fe3O4
ceramic· Fe3O4
Fe₃O₄ (magnetite) is an iron oxide ceramic—a naturally occurring ferrimagnetic compound that combines ferrous and ferric iron in a cubic crystal structure. It is widely used in magnetic applications, pigmentation, and catalysis, where its strong magnetic properties and chemical stability make it attractive for environments demanding both functionality and durability.

Regulatory Screening
Environmental
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.
