High-thermal-conductivity microwave dielectric ceramic material and preparation method thereof
The invention relates to a high-thermal-conductivity microwave dielectric ceramic material and a preparation method thereof, and belongs to the technical field of microwave dielectric ceramics. The preparation method of the high-thermal-conductivity microwave dielectric ceramic material comprises the following steps: mixing a dielectric material and a thermal conductive material, performing compression molding, continuously applying pressure, and performing cold sintering, the applied pressure being not lower than 10MPa, the sintering temperature being not higher than 300 DEG C, and the sintering time being not lower than 1min. The microwave dielectric ceramic with high relative density, high thermal conductivity, low dielectric loss, high Q * f and proper dielectric constant is obtained by matching the dielectric material with the thermal conductive material and performing cold sintering at lower temperature.
