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. Comprising the following steps: acquiring a clean microwave dielectric ceramic substrate, and roughening the surface of the 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 silver-carbon nano material composite layer on the surface of the activated ceramic matrix; and preparing a conductive metal layer on the surface of the silver-carbon nanomaterial composite layer, and passivating the conductive metal layer to obtain the surface-metallized microwave dielectric ceramic material. Through the surface metallization process of the microwave dielectric ceramic material, the electric conductivity of the microwave dielectric ceramic material is remarkably improved, the energy loss of the material applied to a dielectric ceramic filter is reduced, and the reliability of a system can be improved.
