本院研制的锆铝合金消气剂已在灯泡、电子管、稀有气体净化、消气剂泵、碱金属释放器等方面广泛应用。本文介绍了采用真空熔炼、粉末轧制等新工艺生产的消气剂产品的化学成分、相组成和吸气特性。并与国外同类产品作了比较。同时还叙述了该消气剂的使用方法和要求。前言锆铝消气剂含84％锆和16％铝,是由多相金属间化合物组成的合金。它能与各种活性气体发生物理、化学作用产生优异的消气效果,将其装入电真空器件中可提高真空度,保证高可靠长寿命地工作。因此锆铝消气剂已成为一种重要的电真空材料。锆铝消气剂还可用作惰性气体净化剂、消气剂泵的泵芯材料、碱金属释放器的还原剂
The hospital developed zirconium-aluminum alloy getter has been widely used in light bulbs, tubes, rare gas purification, getter pump, alkali metal release and so on. This article describes the chemical composition, phase composition and gettering properties of getter products produced by new processes such as vacuum melting and powder rolling. And compared with similar foreign products. At the same time, the usage and requirements of the getter are also described. Introduction Zirconium-aluminum getters contain 84% zirconium and 16% aluminum, which are alloys composed of heterogeneous intermetallic compounds. It can physically and chemically react with various active gases to produce excellent getter effect, which can be installed in electric vacuum devices to increase the degree of vacuum and ensure high reliability and long service life. Therefore, zirconium-aluminum getters have become an important electrical vacuum materials. Zirconium aluminum getter can also be used as an inert gas purifier, getter pump core material, alkali metal reducer reductant
