摘　　要：SrTiO_3压敏材料的非线性伏安特性和介电性能优良,具有吸收高频噪声、前沿快速上升噪声及自复位等功能,在吸收电感性负载开关浪涌电压、保护双向可控硅开关器件、旁路电容器、微电机等方面应用广泛。本文综述了SrTiO_3压敏材料的导电机理、添加剂以及制备工艺等方面的研究现状,并对其进行了展望。SrTiO3 varistor is characterized by its excellent nonlinear volt-ampere characteristic and high dielectric constant. It＇s high-frequency noise absorption, absorption of noise caused by rapid rise of front and self-reset function have widespread application for absorption of inductive load switching surge voltage and for protection of two-way thyristor switching devices, bypass, micro-machines, etc. The recent developments on the research for the SrTiO3 varistor were reviewed in this paper, which contain the theory of conduction, additive and manufacturing technique, and the evolution was forecast at the same time.
