· JVASP-144739· V4O7

V4O7 is a vanadium oxide ceramic compound that exists in the vanadium-oxygen system, positioned between lower and higher oxidation states of vanadium. While not widely commercialized as a bulk engineering material, vanadium oxides in this family are of significant research and industrial interest for their mixed-valence properties, which enable electrochemical activity and thermal responsiveness. This material and related vanadium oxides are explored for energy storage, catalysis, and smart coatings applications where redox-active ceramics provide advantages over conventional passive 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.
