Abstract:
     Anode of lead-silver alloy is strengthening treated with calcium and mixture of rare earths which lowers content of silver contained in anode of lead-silver alloy by 80%, and in turn cuts down cost of the alloy anode greatly. Alloy anode according to this invention has superior mechanical and corrosion-resistant performance, can be used to produce electrolytic zinc with lead content lower than 0.005% in industrial quantity, and because of 3-7 times of raise of corrosion resistance can be used longer than current ones, the cost of the anode is lowered to 2kg/ton zinc in electrolysis of zinc. The lead-silver-calcium-rare-earths alloy anode can be used in electric metallurgy such as electrolysis of zinc or copper.
