Microwave dielectric ceramic material and surface metallization process and application thereof
The invention belongs to the technical field of ceramic materials, and particularly relates to a microwave dielectric ceramic material and a surface metallization process and application thereof. The surface metallization process comprises the following steps: roughening the surface of a clean microwave dielectric ceramic substrate to obtain a roughened ceramic substrate; carrying out precious metal activating treatment on the surface of the roughened ceramic matrix, and then carrying out peptizing treatment to obtain an activated ceramic matrix; preparing a graphene oxide doped copper composite layer on the surface of the activated ceramic matrix; and preparing a nickel layer on the surface of the graphene oxide doped copper composite layer, and passivating the nickel layer to form a passivation layer, thereby obtaining the microwave dielectric ceramic material with the metalized surface. According to the surface metallization process of the microwave dielectric ceramic material, the abrasion resistance and the corrosion resistance of the microwave dielectric ceramic material are remarkably improved, the energy loss of the material applied to a dielectric ceramic filter is reduced, the reliability of a system can be improved, meanwhile, the use amount of precious metal is reduced, and the production cost is reduced.
