随着国民经济及国防工业的发展,高纯铟及其化合物已广泛地应用于半导体、原子能及仪表制造等方面。我们曾于1971年7月以邗江化工厂综合回收之品位为60.8％的铟合金作原料,做了试制提纯工作,继之又根据我们小型试验的初步探讨以省机械局的99.9～99.99的工业铟为原料,做了试生产工作,获得了99.999％的高纯铟。我们曾去使用单位征求了部分用户的意见,根据使用单位反映,高纯铟质量尚可,用其所制之原件测试参数均系正常。 1.由铟合金制取高纯铟试验 1.1 试验流程:如图1。 1.2 原理和实践
With the development of the national economy and national defense industry, high purity indium and its compounds have been widely used in the fields of semiconductors, atomic energy and instrumentation. In July 1971, we used the indium alloy with a grade of 60.8% recovered from Yongjiang Chemical Plant as a raw material to make a trial purification work. After that, according to the preliminary discussion of our small-scale experiment, we took the industry of 99.9-99.99 of the Provincial Bureau of Machinery Indium as a raw material, made a trial production work, obtained 99.999% of high-purity indium. We have to use the unit to solicit the views of some users, according to the use of units reflect the quality of indium can still be used, with the original test parameters are normal. 1.
