摘要
对影响氧化铝陶瓷介电性能(介电常数、介电损耗和介电强度)的各种因素进行了较为系统的评述,并对相应的影响机理进行了分析和探讨。希望能为电真空用氧化铝陶瓷的质量控制和检验提供理论依据,同时也为工艺方法(包括材料工艺和电真空器件工艺)的选择提供有益的技术参考。
The factors influencing on dielectric properties of alumina,which were widely used in the field of vacuum electronics,were reviewed in detail in this paper.Subsequently,the corresponding mechanisms were analyzed and discussed.It is anticipated that the results should provide a helpful reference for quality control of alumina ceramics,as well as the technologies with respect to materials and vacuum electronics.
