摘要：An improved electrode having a surface mixture of nickel and porous nickel produced by applying a paste mixture of NiAl2 and Ni3B together with a vehicle to a substrate. After burning off the vehicle and firing in air at a temperature of 450 DEG to 650 DEG C. and thereafter sintering at a temperature of 800 DEG to 900 DEG C. in nitrogen, the coating on the substrate contains Ni2Al3, NiAl2B and nickel together with a thin overlayer of B2O3. After removing the intermetallic aluminum, boron and boron oxide by dissolution with sodium hydroxide, the surface of the substrate contains Raney nickel supported on a structure of nickel. The resulting electrodes can be used as cathodes in water or brine electrolysis cells.
