摘要
介绍了W -ThO2 阴极材料的应用与性能特点 ,讨论了影响W -ThO2 阴极材料使用性能的因素和ThO2的作用机理 ,总结了W -ThO2 阴极材料研究中存在的主要问题。介绍了几种新近发展起来的新型W -ThO2 阴极材料 ,并提出了现阶段W -ThO2 阴极材料研究的发展方向。
In this paper, the application and characteristics of thoriated tunsgten cathode materials have been reviewed. The factors influencing the service property of thoriated tungsten cathode materials and the action mechanism of ThO 2 in cathode have been discussed. The major problems on the research and development of thoriated tungsten cathode materials are presented. Some newly developed W-ThO 2 cathode msterials have been introduced. The further researching direction of thoriated tungsten cathode materals is pointed out.
