综述了粉体尺寸、烧结温度、保温时间、掺杂剂的选择及含量等对 TiO2压敏陶瓷压敏电压、非线性系数、介电损耗和介电常数等电性能以及晶体微观结构影响的研究现状，并指出 TiO2压敏陶瓷在小型化和多功能化等方面的发展是今后重要的研究方向。
The effects of some experiment parameters,such as powder size,sintering temperature,soaking time,the type of dopant and their content on electrical properties of TiO2 varistor ceramics are summarized,as well as their crystal microstructures.The electrical properties include varistor voltage,nonlinear coefficient,dielectric loss,dielectric constant and so on.It is pointed that the research focus is on the development tendency in miniaturization and multi-functionalization of TiO2 varistor ceramics.
