雷达和微波通讯用的电子管,要求材料具有良好的导电性和导热性以及耐高温特性。材料必须均匀、无瑕和纯度高,以使真空管的工作特性均匀。雷达和微波通讯用电子管的材料的选择,主要是根据导电性、导热性和高温特性。由于原料的价格比管子组件的价格要低得多,所以最高等级的或最纯的材料,往往是最经济的。在制造速调管、行波管或类似的高真空器件时,遇到了一些复杂的冶金问题。
Radar and microwave communication with the tube, the material requires good electrical conductivity and thermal conductivity and high temperature characteristics. The material must be uniform, flawless and of high purity so that the working characteristics of the vacuum tube are uniform. Radar and microwave communications tube material selection, mainly based on conductivity, thermal conductivity and high temperature characteristics. Because the price of raw materials is much lower than the price of pipe components, the highest grade or purest material is often the most economical. In the manufacture of klystrons, traveling wave tubes or similar high vacuum devices, some complex metallurgical problems are encountered.
