Abstract：In this paper，a composite system is selected，which includes MgTiO3 with high Q-value and Ba6-3xNd8+2xTi18O54 with high dielectric constant at high frequencies. The composite system is made into the y•MgTiO3-（1-y）Ba6-3xNd8+2xTi18O54 composite powder with specific composition distribution，which prepared by liquid phase encapsulation technology combined with high energy ball milling process. In addition，the dielectric layer of ceramic capacitor with special “shell-core” structure was prepared by two-step sintering method. The mass production of MLCC with frequency and high Q-value was realized. The implementation of this project will enable enterprises to successfully realize the mass production of related products，meet the huge military market demand，change the pattern of similar products depending on imports，and ensure national defense security. It will not only have strong social benefits，but also bring greater economic benefits.
