Calcium Oxide
Calcium Oxide is a highly insoluble thermally stable Calcium source suitable for glass, optic and ceramic applications. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems.
