· JVASP-34193· Fe7O8

Fe7O8 is an iron oxide ceramic compound belonging to the family of mixed-valence iron oxides, intermediate between magnetite (Fe3O4) and hematite (Fe2O3) in composition. This material is primarily of research and industrial interest for applications requiring iron oxide phases with specific magnetic and structural properties, including magnetic recording media, pigments, and catalytic applications where controlled iron oxidation states are beneficial.

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.
