· JVASP-48315· Fe8O9

Fe8O9 is an iron oxide ceramic compound that exists as an intermediate phase in the iron oxide system, positioned between magnetite (Fe3O4) and hematite (Fe2O3). While not widely commercialized as a primary engineering material, Fe8O9 is of significant interest in materials research and industrial processes involving iron oxidation, oxygen storage, and thermal processing of iron-bearing materials. Its notable characteristics—including mixed valence iron states and moderate density—make it relevant to high-temperature applications, catalysis, and oxygen-transport systems where intermediate iron oxide phases offer advantages over pure binary oxides.

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.
