Copper oxide, a mixed valency partially substituted by fluorine, and component containing

摘要

The invention concerns a copper oxide of mixed valency of a structure derived from perovskite containing cations with solitary doublet, which results from a superconductor ceramic composition which has cations with solitary doublet and a laminar macrostructure, by partial substitution of fluorine for the oxygen in the oxygen atom network. Application: electric and electronic industry.
