High-dielectric microwave ceramic dielectric material, and preparation method and use thereof
The invention discloses a high-dielectric microwave ceramic dielectric material, and a preparation method and an application thereof. The high-dielectric microwave ceramic dielectric material is composed of a main material and an additive and is characterized in that the main material has a structural formula of X(Ba1/2Li)(Mg1/3Ta2/3)O3-(1-X)SrTiO3, wherein 0.55<=X<=0.75; the additive is one or more of ZnO, MnO2, Nb2O5, Li2CO3 and CaCO3. The weight percentage of the main material is 95-99%, and the weight percentage of the additive is 1-5%. The main material compound is prepared by a chemical co-precipitation method, a calcining synthetic temperature is lower than that of a traditional solid phase method, and the method has the characteristics of low energy consumption, high material purity, uniform composition and high surface activity. Microwave ceramic devices after sintering are good in consistency and dense in ceramic bodies, and can better adapt to application requirements of high-quality microwave devices.
