· Fe7 O8

Fe₇O₈ is a mixed-valence iron oxide semiconductor belonging to the magnetite family, characterized by iron in both +2 and +3 oxidation states. This material is primarily investigated in research contexts for energy storage, catalysis, and magnetism applications, where its semiconducting behavior and magnetic properties offer potential advantages over simpler iron oxides like Fe₂O₃ or Fe₃O₄ in specific electrochemical and sensing environments.

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.
