Abstract:
    A hydrogen-evolution electrode comprising an electrically conductive substrate having thereon a coating comprising a chromium component, a titanium component and an oxide of at least one metal selected from the group consisting of nickel and cobalt, said chromium component and titanium component being present in proportions, in terms of atomic percentage, of 0.5 to 40% and 0.1 to 10%, respectively. Accordingly, the electrode has a life several times as long as that of the conventional electrodes, and can exhibit an advantageously low hydrogen overvoltage for a prolonged period of time. Also, the electrode can be advantageously employed to produce an alkali product improved in purity. In the production, when the above-mentioned mixture is subjected to granulation and the obtained granules are melt-sprayed, there can be obtained the desired electrode having excellent properties with respect to catalytic activity and durability in high spraying yield.
