· Ca2 V4 O8

Ca₂V₄O₈ is a mixed-valence calcium vanadate ceramic compound and semiconductor material belonging to the vanadium oxide family. This material is primarily of research and developmental interest for energy storage and electrochemical applications, where vanadium oxides are explored as cathode materials, ion conductors, and catalysts due to their variable oxidation states and structural flexibility. Engineers consider vanadium oxide systems for next-generation battery technologies, supercapacitors, and catalytic devices where the ability to shuttle ions and electrons under charge-discharge cycling is advantageous over conventional oxides.

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.
