· JVASP-49827· CaCu2O2

CaCu2O2 is a mixed-valence copper oxide ceramic compound containing calcium and copper in a defined stoichiometric ratio. This material belongs to the family of copper-based oxides and is primarily investigated in research contexts for its potential electronic and catalytic properties, particularly in applications requiring copper oxide's semiconducting or catalytic behavior combined with calcium's stabilizing influence. The compound represents an intermediate composition within the CaO–CuO system and is of interest to materials scientists exploring novel ceramic phases for energy conversion, catalysis, or functional ceramic applications.
