Abstract

The present application discloses a copper oxide-doped composite microwave dielectric ceramic and a preparation method thereof. In the copper oxide-doped composite microwave dielectric ceramic, the mass proportion of BaTi4O9 is 82wt%, and the mass proportion of copper oxide is 3wt%. The balance is BaZn2Ti4O11. Copper oxide-doped multiphase microwave dielectric ceramics were synthesized at one time by solid-state method. The invention effectively improves the sintering characteristics of dielectric ceramics through copper oxide modification, reduces the sintering temperature, and obtains ceramic materials with high density. It is synthesized by a solid-phase method. Compared with the traditional process, the process has the advantages of good repeatability, low equipment requirements, low cost and convenient industrialized large-scale production.
