Calcium vanadium oxide (CaVO₂) is an inorganic ceramic compound combining calcium, vanadium, and oxygen into a mixed-metal oxide structure. While not widely commercialized as a bulk engineering material, CaVO₂ and related vanadium-bearing ceramics are primarily of research interest for applications requiring thermal stability, mixed-valence redox behavior, and high-temperature phases. The material's vanadium content makes it relevant to emerging technologies in energy storage (cathode materials for batteries), catalysis, and advanced refractory systems, where vanadium oxides offer variable oxidation states and thermal robustness compared to conventional single-oxide ceramics.
