Industrial pulse energy storage multilayer ceramic capacitors (MLCC) are important components for the development and production of electronic starting devices in China. In view of the shortcomings of large size, short life and low reliability of organic film capacitors, SrTiO₃ and CaTiO₃ based pulse energy storage dielectric ceramics were prepared by traditional solid-state reaction method in this study. The effects of sintering aid doping and Sr²⁺/Ca²⁺ mutual doping on the dielectric properties of ceramic materials were studied, and the property of MLCC based on (Sr,Ca)TiO₃ were further prepared and investigated. The results show that the dielectric constant of SrTiO₃ materials can be improved by adding the sintering aid with a mass ratio of 1.0%, such as the introduction of trace Bi³⁺, while Bi³⁺ has no obvious effect on the CaTiO₃ based materials. Doping of Mn element can effectively inhibit the reduction of Ti⁴⁺ during high-temperature sintering and reduce dielectric loss. Moreover, the addition of sintering aid can effectively reduce the sintering temperature of ceramic powder and improve the compactness of the material. The MLCC prepared from (Sr_xCa_1-x)TiO₃ material can maintain high dielectric constant and low dielectric loss, at x=0.4, the dielectric loss tanδ=1.8×10^-4, the breakdown strength is 59.38 V/μm, and the high and low temperature discharge current change rate is ±7%, which shows good discharge stability. In addition, no matter it is at room temperature or high temperature (125 ℃), the sample has no failure after 1000 cycles of discharge experiment. Therefore, the as-obtained (Sr, Ca)TiO₃ based ceramic dielectric material can be a promising pulse capacitor with relatively excellent capacity stability and high reliability under different electric field strength.
