PURPOSE:To obtain an anode material for producing electrolytic MnO2 replaceable with the conventional Ti anode material, enabling electrolysis at high current density and causing no corrosion even while being not electrified by providing a compsn. consisting of a prescribed wt.% of Ni and the balance Ti with inevitable impurities. CONSTITUTION:The title anode material is composed of 0.05-0.5wt.% Ni and the balance Ti with inevitable impurities or of 0.05-0.5wt.% Ni, 0.01-5wt.%, in total, of Pt, Rh, Au, Pd, Ir, Os and Ru and the balance Ti with inevitable impurities. The Ti alloy contains Ti2Ni precipitated as an intermetallic compd. and the Ti2Ni prevents the growth of a passive film and the rise of bath voltage even when high density electric current is supplied, so current density can be increased and the productivity of electrolytic MnO2 is improved. |
