Barium titanate-based energy storage ceramic material and preparation method thereof
The invention relates to the technical field of dielectric ceramic materials, in particular to a barium titanate-based energy storage ceramic material and a preparation method thereof.The preparation method comprises the steps that BaCO3, TiO2, Bi2O3, MgO, Nb2O5 and CaCO3 serve as raw materials to prepare barium titanate-based ceramic powder; putting the barium titanate-based ceramic powder into a ball milling tank, carrying out predetermined treatment, pressing into a green body, and pre-sintering to obtain a pre-sintered product; putting the pre-sintered product into the ball-milling tank, carrying out pre-treatment again, and pressing into a wafer; the wafer is sintered in a muffle furnace according to sintering conditions, and the barium titanate-based ceramic material is obtained.The barium titanate-based ceramic material is finally prepared with BaCO3, TiO2, Bi2O3, MgO, Nb2O5 and CaCO3 as raw materials, the breakdown strength and insulativity are improved, the energy storage density and energy storage efficiency of the material are improved accordingly, meanwhile, harmful elements are not used in the raw materials, and the barium titanate-based ceramic material is environmentally friendly. The environment is not polluted, and the problem that an existing linear dielectric material with high energy storage density can pollute the environment is solved.
本发明涉及电介质陶瓷材料技术领域，具体涉及一种钛酸钡基储能陶瓷材料及其制备方法，包括以BaCO3、TiO2、Bi2O3、MgO、Nb2O5、CaCO3为原料制备钛酸钡基陶瓷粉体；将所述钛酸钡基陶瓷粉体放入球磨罐中进行预定处理后压成坯体进行预烧，得到预烧产物；将所述预烧产物放入球磨罐中再次进行预定处理后压成圆片；将所述圆片在马弗炉中按烧结条件进行烧结，得到钛酸钡基陶瓷材料，本发明通过以BaCO3、TiO2、Bi2O3、MgO、Nb2O5、CaCO3为原料最终制备得到的钛酸钡基陶瓷材料，提高了击穿强度和绝缘性，从而提高了材料的储能密度和储能效率，同时原料中并未使用有害元素，不会对环境造成污染，解决了现有的高能量存储密度的线性电介质材料会对环境造成污染的问题。
