· JVASP-48815· Fe4O5F3

Fe4O5F3 is an iron oxide-fluoride ceramic compound that combines iron oxides with fluorine, creating a mixed-valence iron phase material. This is a research-stage compound rather than an established commercial material; it belongs to the family of iron oxyhalides being investigated for potential applications in energy storage, catalysis, and electronic devices where the fluorine substitution modifies the crystal structure and electrochemical properties compared to conventional iron 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.
