Dielectric ceramic material with high breakdown strength and high energy storage density and preparation method thereof
The invention discloses a preparation method of a dielectric ceramic material with high breakdown strength and high energy storage density. The preparation method comprises the following specific steps: weighing 40 to 50 weight percent of BaCO3, 5 to 10 weight percent of B2O3, 33 to 38 weight percent of SiO2 and 5 to 10 weight percent of ZnO; carrying out ball milling, drying, melting and quenching on the weighed reagents, and carrying out ball milling on the quenched glass to obtain glass powder; mixing the prepared Ba0. 3Sr0. 7TiO3 powder with glass powder to obtain mixed powder, adding a PVA (Polyvinyl Alcohol) reagent, performing spray drying, and performing compression molding to obtain a green body; and sintering the green body to obtain the dielectric ceramic material with high breakdown strength and high energy storage density. According to the high-breakdown-strength and high-energy-storage-density dielectric ceramic material and the preparation method thereof, the melting temperature of glass and the sintering temperature of a ceramic medium are remarkably reduced, and the breakdown performance and the energy storage characteristic of dielectric ceramic are improved.
本发明公开了一种高击穿强度高储能密度介电陶瓷材料的制备方法，具体步骤如下：称取重量百分比为40‑50％的BaCO3，重量百分比为5‑10％的B2O3，重量百分比为33‑38％的SiO2和重量百分比为5‑10％的ZnO；将称取的试剂进行球磨、干燥、熔化和淬冷，将淬冷后的玻璃球磨成玻璃粉体；将制备得到的Ba0.3Sr0.7TiO3粉体与玻璃粉体混合得到混合粉体，添加PVA试剂，喷雾干燥，压模后得到生胚；将生胚进行烧结，得到高击穿强度高储能密度介电陶瓷材料。本发明还公开了一种高击穿强度高储能密度介电陶瓷材料，本发明显著降低玻璃的融熔温度和陶瓷介质的烧结温度，提高基介电陶瓷的击穿性能和储能特性。
