摘要
研究了４种复合氧化物（ＰｂＯ－Ｂｉ２Ｏ。－Ｂ２Ｏ３，ＭｎＯ－Ｂｉ２Ｏ３，Ｎａ２Ｏ－ＳｉＯ２和ＬｉＮｂＯ３）为扩散剂对半导化的ＳｒＴｉＯ３基陶瓷显微结构、压敏和介电特性的影响．在实验基础上，提出了新的晶界势垒模型．
The influence of four composite oxides (PbO-Bi2O3-B2O3, MnO-Bi2O3,Na2O-SiO2 and LiNbO3) as diffusants on the microstructure and voltage-sensitive characteristics of SrTiO3-based semiconductor ceramies was studied and a new potential barrier model on grain boundary was proposed. A series of multi-functional materials with perfect voltage-sensitive and dielectric performance were obtained.
