Abstract
PURPOSE: To develop a cathode with superior alkali resistance and low hydrogen overvoltage for electrolysis of an aq. soln. of an alkali chloride by removing part of the components of an alloy of a specific compsn. from the alloy surface by etching to render the alloy porous.
CONSTITUTION: A cathode for electrolysis of aq. soln. of an alkali chloride is made of alloy of one or more kinds of first group metals consisting of Cr, Mn, Fe, Ti, Ta, Nb, V, Si, Zr, GE, Cu, Y and la, and one or more kinds of second group metals consisting of Ni, W, Ag, Co and Mo. The electrode surface is etched to 0.01W50 μ depth to reduce the first group metals to Fe; 15W90% and Cr; 0W20%, and a Fe- Cr-Ni alloy contg. Ni; 10W75% is used. By the etching a cathode is obtd. having 105W108/cm2 of fine pores on the surface, an electric double layer capacity of 5000 μF/cm2 and low hydrogen overvoltage.
