摘要
利用共沉淀法,以硝酸盐为原料,制备出组分均一的PZT95/5型陶瓷微粉,引入反应烧结和热压烧结的方法。经550℃热处理,1130℃热压烧结后,得到致密的PZT95/5型陶瓷材料,同时该材料具有高的击穿场强,为它在爆电换能方面的应用提供了更广阔的前景.
A wet procedure to prepare stoichiometric and homogeneous Zr rich PZT powders was described. The hydroxide precursor was prepared by coprecipitation from a mixed nitrate solution containing Pb2+, Zr4+, Ti4+ ions at pH 9. The precursor pellets were calcined at 550degreesC for 0.5h and reactively sintered at 1130degreesC for 2 h under hot-press, then a density of 98% theoretical. density was obtained, as well as the samples exhibited good ferroelectrics properties.
