Microwave ceramic powder material as well as preparation method and application thereof

The invention discloses a microwave ceramic powder material as well as a preparation method and application thereof, and belongs to the technical field of electronic functional materials and devices. The multi-component sintering aid is added into the main crystal phase xMgO-yZnO-zTiO2, the sintering aid can promote sintering of the microwave ceramic powder material, the microwave ceramic powder material can be sintered in the temperature range of 950-1150 DEG C, the density of a sintered ceramic body is higher than 98%, the dielectric constant of the sintered microwave ceramic powder material is 20-30, and the dielectric loss is tan delta lt; compared with the prior art, the powder material has the advantages that the temperature coefficient of capacitance (TCC) is smaller than or equal to +/-30 ppm/DEG C, the insulation resistivity is larger than 1012 omega.cm, the electrical performance and the process matching window of the powder material are improved, the powder material can be matched with inner electr
