摘要
介绍了电解法制备高纯金的基本原理和试验过程,与其它方法相比较,方法具有工艺技术参数稳定、易控、产品的杂质元素含量低、质量稳定、易于批量化生产、流程短、成本低等优点,特别适合对高纯金需求量大的行业如键合金丝等生产的需要。。
The high pure gold used for gold bonding wires was prepared by the electrolytic method. Com- pared with other methods, this method has many advantages, such as： the process technology parameters are stable and easy to control; the content of impurity elements in products is low; the quality is stable; mass production is easy to realize; production flow is short; and the cost is low. It is specially suited for industries having high demand for high pure gold, for example, gold bonding wires.
