高纯金是电子技术中的重要材料。在晶体管和各种集成电路中是良好的欧姆接触材料。此外,在精密仪表和测温元件中均有广阔的应用前景。这些领域中对金的纯度要求较高,一般均在99.999％以上。为了满足国防军工和国民经济对高纯度金的要求,我们从1962年开始研制高纯金,通过十多年的 High-purity gold is an important material in electronic technology. Good ohmic contact material in transistors and various integrated circuits. In addition, the precision instruments and temperature measurement devices have a broad application prospects. The purity of gold in these areas require a higher, generally above 99.999%. In order to meet the requirements of the national defense industry and the national economy for high-purity gold, we started to develop high-purity gold from 1962, and after more than a decade
