The invention discloses a preparation method of a microwave ceramic material with a high dielectric constant, and belongs to the technical field of preparation of microwave ceramic materials. The microwave ceramic material with the high dielectric constant is composed of main components and auxiliary agents, wherein the main components are BaSn4O9 and Ba2Sn9O20, and the auxiliary agents are any two or more of Y2O3, CaCO3, Dy2O3, ZnO and CuO. According to the invention, the test results prove that compared with the traditional production process, the dielectric constant of the microwave ceramicdielectric material obtained by the invention is obviously improved by adding the water washing and drying process steps into the preparation method of the microwave dielectric ceramic, wherein the dielectric constant [epsilon]r of the microwave ceramic dielectric material is continuously adjustable between 60 and 70, the requirement for serialization of the dielectric constant of the microwave ceramic is met, and the quality factor Q and the frequency temperature coefficient tau f both meet the requirement.
