· V4O3F5

V4O3F5 is a vanadium oxyfluo ride ceramic compound combining vanadium oxide with fluorine in its crystal structure. This is a specialized research material rather than a widely commercialized ceramic, belonging to the family of mixed-anion ceramics that exhibit unique electrochemical and structural properties from the fluorine substitution in the oxide lattice. The fluorine incorporation typically enhances ionic conductivity and chemical stability compared to conventional vanadium oxides, making it of particular interest in energy storage and electrochemical device applications.

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.
