氧化物阴极基金属材料中激活元素的存在状态及其分布对该阴极的活性及寿命有很大的影响。目前国内生产Ni-W-Ga合金作为彩色显象管和超高频管用氧化物阴极基金属材料已有多年,但对该合金尚未作详细的分析研究,对该合金中Ga的存在状态也有不同的看法。这在一定程度上影响该合金的生产和使用。为此,今年三月份在常州全国电真空高可靠长寿命阴极基金属材料会议上确定由几个单位分别分析研究Ni-W-Ga合金中Ga的存在状态及其分布,以便对该合金作出较全面的评价。
The existence state and distribution of the active elements in the oxide cathode base metal material have a great influence on the activity and life of the cathode. At present, Ni-W-Ga alloy has been used for many years as the cathode material of cathode tubes for CRT and UHF tube. However, the detailed analysis of this alloy has not yet been made and the existence of Ga in this alloy is different the opinion of. This to a certain extent affect the production and use of the alloy. To this end, in March this year, Changzhou in the national vacuum high reliability and long-life cathode metal materials meeting identified several units were analyzed Ni-W-Ga alloy in the presence of Ga and its distribution in order to make the alloy more Comprehensive evaluation.
