摘要
研究了Bi2O·33TiO2和MgTiO3的加入量对SrTiO3基高压陶瓷电容器材料性能的影响,并用扫描电子显微镜(SEM)对样品进行形貌观察。实验结果表明:加入适量的Bi2O·33TiO2能提高材料的介电常数和降低介质损耗,适量MgTiO3的加入改善了材料的温度特性,且其晶粒尺寸均匀。
The effect of the additives Bi2O3·3TiO2 and MgTiO3 on the properties of SrTiO3 based ceramics was studied, and scanning electron microscope（SEM） was used to observe the morphology of the products. The result indicated that dielectric constant could be increased and loss tangent could be decreased by additive Bi2O3·3TiO2, The material＇s temperature characteristic was improved by additive MgTiO3, and the its grain size was homogeneous.
