Medium dielectric constant ceramic powder and preparation method thereof
The invention relates to the technical field of high-performance ceramic powder, in particular to medium-dielectric-constant ceramic powder and a preparation method thereof.The preparation method comprises the following steps that S1, MgO and ZrO2 are subjected to ball milling, then dried and sieved, and then pre-sintered to obtain first-grade MgZrO3 powder; s2, carrying out ball milling on CaO and ZrO2, drying, sieving, and pre-sintering to obtain first-grade CaZrO3 powder; s3, mixing the first-stage MgZrO3 powder and the first-stage CaZrO3 powder, performing second-stage ball milling, drying, sieving and sintering to obtain the medium-dielectric-constant ceramic powder. According to the invention, a novel microwave dielectric ceramic material system with good dielectric property is explored according to the intrinsic characteristic relationship of elements.
