【摘要】：采用固相反应法制备电子工业用BaZr_xTi_(1-x)O_3材料,研究不同烧结温度和时间的物相组成、显微组织形貌和介电性能。结果表明,随着烧结温度的升高,BaZr_xTi_(1-x)O_3中的物相组成没有明显变化,但结构由四方体变为立方体;当烧结温度从1 250℃升高至1 350℃时,材料的平均晶粒尺寸从29μm增加至39μm;当晶粒尺寸较小时,材料主要形成90°畴和180°畴,增加晶粒尺寸,材料主要形成180°畴。
[Abstract]:BaZr_xTi_ (1-x) O _ 3 materials for electronic industry were prepared by solid state reaction method. The phase composition, microstructure and dielectric properties of BaZr_xTi_ (1-x) O _ 3 were studied at different sintering temperature and time. The results show that the phase composition of BaZr_xTi_ (1-x) O _ 3 does not change obviously with the increase of sintering temperature, but the structure changes from tetragonal to cubic. When the sintering temperature was raised from 1 250 鈩，
