CaCuO2F

CaCuO₂F is a mixed-valence copper oxide fluoride ceramic compound containing calcium, copper, oxygen, and fluorine elements. This material belongs to the family of oxyfluoride ceramics and remains primarily in the research and development phase, with applications being explored in solid-state chemistry and materials science rather than established industrial use. The incorporation of fluorine into the copper oxide lattice creates novel crystal structures and electronic properties that distinguish it from conventional cuprate ceramics, making it of interest for fundamental studies in superconductivity, magnetism, and ionic conductivity.
