摘要：
A corrosion-resisting anode made of a planar sheet of alloyed lead, to be used in industrial cells wherein acidic solutions are circulated, for the electrowinning of non-ferrous metals, such as zinc and cadmium, is characterized in that it is composed by 98.9 to 99.9% of lead, from 0.1 to 1% calcium and from 0 to 0.1% silver.
