摘要：
An improved insoluble anode for electrowinning is described which comprises a graphite substrate covered by a tight fitting sheet of a nonconductive electrolytically inert mesh material over which covered substrate is electrodeposited a layer of lead dioxide. The anode is formed by covering the graphite substrate with a sheet of the inert mesh material and thereafter electrodepositing lead dioxide thereon until a smooth layer of lead dioxide completely covers the mesh material. The anodes are electrolytically stable and are not susceptible to cracking.
