ceramic

· JVASP-56700· K3VCO8

K3VCO8 is a ceramic compound containing potassium, vanadium, and oxygen, representing a mixed-metal oxide in the vanadate family. This material is primarily of research and development interest rather than a widely commercialized engineering ceramic, with potential applications in electrochemical systems, catalysis, and solid-state ion conductors where vanadium oxides are known to exhibit useful redox and ionic properties. Engineers would consider this material for advanced applications requiring specific electronic or catalytic behavior, though its practical use remains limited to specialized research contexts and prototype development.
