Abstract: This invention provides a method to make core-shell structured dielectric particles which consist of a conductive core and at least one layer of insulating dielectric shell for the application of multilayer ceramic capacitors (MLCC). The use of said core-shell instead of conventionally solid dielectric particles as the capacitor's active layers simplifies the MLCC manufacturing processes and effectively improves the MLCC properties. In particular, the use of core-shell particles with a thin shell of high permittivity dielectric material improves the capacitance volumetric efficiency, and the use of core-shell particles with a thick shell of dielectric will improve capacitor device's energy storage capacity as the results of improved electrical and mechanical strength.
