氧化锌压敏陶瓷及其元件研究进展

Progress in Research on ZnO Ceramics and Varistors

介绍了氧化锌压敏陶瓷在次晶界现象、几何效应以及高温热释电等方面的应用基础研究成果,指出氧化锌压敏电阻器的发展方向为片式化和提高能量耐受能力。

Some research results of ZnO ceramics are reviewed in this paper,including subgrainboundary phenomena,dimensional effect and high-temperature pyroelectricity.It is suggested that the research on ZnO varistors should focus on chip varistors and improving energy capability.
