Lead zirconate stannate thick-film ceramic material with high breakdown electric field resistance and preparation method of lead zirconate stannate thick-film ceramic material
The invention provides a lead zirconate stannate thick-film ceramic material with high breakdown electric field resistance and a preparation method of the lead zirconate stannate thick-film ceramic material. The preparation method comprises the steps of weighing raw materials according to a preset stoichiometric ratio, placing the raw materials in a nylon ball milling tank, adding excessive 3wt% of PbO, and carrying out ball milling to obtain a first product; drying and sieving the first product to obtain first ceramic powder; placing the first ceramic powder in a muffle furnace for pre-sintering, and after pre-sintering, doping the glass powder into the pre-sintered first ceramic powder according to different mass fractions; performing secondary ball milling, drying and sieving to obtain second ceramic powder; placing in a barreling tank, adding a dispersing agent and a solvent for barreling to obtain premixed slurry, adding a binder for continuous barreling, then adding the solvent, the binder and a plasticizer for continuous barreling to obtain tape casting slurry; and carrying out tape casting on the tape casting slurry through a tape casting machine, and carrying out warm isostatic pressing and glue discharging sintering to obtain the lead zirconate stannate thick-film ceramic material with high breakdown electric field resistance. The thick-film ceramic with high breakdown electric field resistance and high energy storage density is formed.
本发明提供一种高耐击穿电场的锆锡酸铅厚膜陶瓷材料及其制备方法，包括以下步骤：将原料按照预设化学计量比称取放置于尼龙球磨罐并加入过量3 wt%PbO，进行球磨得到第一产物；将第一产物进行烘干过筛得到第一陶瓷粉；将第一陶瓷粉置于马弗炉中进行预烧，预烧后将玻璃粉按不同质量分数分别掺入预烧完的第一陶瓷粉中；进行第二次球磨和烘干过筛得到第二陶瓷粉；置于滚磨罐，加入分散剂和溶剂进行滚磨后得到预混浆料，加入粘结剂继续滚磨后再加入溶剂、粘结剂和塑化剂继续滚磨得到流延浆料；对流延浆料通过流延机进行流延成型，再经过温等静压和排胶烧结后得到高耐击穿电场的锆锡酸铅厚膜陶瓷材料。本发明形成高耐击穿电场和高储能密度的厚膜陶瓷。
