METHOD OF PRODUCING A DIELECTRIC WITH PEROWSKITE STRUCTURE

摘要

Method for producing a dielectric having perowskite structure on the basis of stoichimetrical alkaline earth titanates, alkaline earth zirconates, alkaline earth stannates and mixed crystals thereof with an admixture of a copper compound, wherein an admixture of eutectic-forming metal oxides of the formula CuO.MeOx, which can in practice not be built into the perowskite lattice, are added to the stoichiometrical perowskite structure and wherein the mixture of compounds is sintered at a partial oxygen pressure of 0.2 to 1 Bar in the temperature range from 1000 - 1250.degree.C, MeOx in the abovementioned formula being the oxide of at least one element of group III, V, VI or VII of the Periodic System of Elements(P.S.E.).
