Abstract: Disclosed herein is a cathode having an electroconductive substrate and a porous surface. The porous surface is characterized by containing a major portion of nickel and a hydrogen overvoltage reducing amount of molybdenum. The molybdenum may be present as elemental molybdenum, as an alloy with nickel, or as a molybdenum compound. Also disclosed is an electrolytic cell having an anode, a cathode, and a separator between the anode and cathode, where the cathode is characterized by a porous surface having a major portion of nickel and a hydrogen over voltage reducing amount of molybdenum, which molybdenum may be present as elemental molybdenum, and molybdenum alloy with nickel or a molybdenum compound.Further disclosed is a method of electrolyzing an alkali metal chloride brine by passing an electrical current from an anode to a cathode to evolve chlorine at the anode and hydroxyl ion at the cathode.

Abstract: Disclosed herein is a method of preparing porous transition metal catalysts for a solid polymer electrolyte electrolytic cell. Also disclosed is the use of solid carriers for carrying oxidant to a depolarized solid polymer electrolyte cell. Finally, there is disclosed the use of an intercalation compound of carbon and fluorine as the cathode catalyst.

Abstract: Disclosed is a method of casting silicon metal. Silicon metal expands upon solidification. According to the disclosed method a void volume of from 1 to 10 percent of the silicon metal, basis molten silicon metal, is established within the molten silicon metal. The void volume is capable of being decreased in volume upon the solidification of the silicon metal. In this way, the increase in volume of the silicon metal upon solidification is offset.

Abstract: Disclosed is a method of mounting a silicon member intended for use as an anode in the lead base of a chlor-alkali electrolytic cell. According to this invention, the amount of molten lead provided on the cell base in contact with the stem or base of the anode is low enough to avoid subjecting the silicon member to excessive thermal stresses.

Abstract: Disclosed is a method of joining a silicon metal work piece to a second metallic work piece. In the disclosed method, an adherent surface is provided on the silicon work piece. A pool is then provided on the surface of the silicon, in contact with the adherent surface and with the second metallic work piece. The pool is then solidified to join the silicon work piece and the second work piece.
