一、前言有色金属电解工厂对阴极沉积物提出了一定要求:它必须致密,并且具有光滑的表面,尽量少被未洗净的残余电解液所污染,气体和有害杂质含量最少等。近年来对阴极沉极物组织结构的研究引起了较大的兴趣。因为,阴极沉积物的质量基本上取决于它的组织结构。阴极沉积物愈致密,其气体含量及表面积 I. INTRODUCTION The non-ferrous metal electrolysis plant poses certain requirements for cathodic deposits: it must be dense and has a smooth surface, with as little contamination as possible with unwashed residual electrolyte, with minimal gas and other harmful impurities. In recent years, the research on the structure of cathodic sinker has aroused great interest. Because, the quality of cathode sediment basically depends on its organizational structure. The darker the cathode deposits, the gas content and the surface area
