    摘要: Disclosed is a method of electrolyzing alkali metal chloride brines by passing an electrical current from an anode in an aqueous alkali metal chloride anolyte liquor through a permeable barrier to a cathode in an aqueous catholyte liquor, whereby to evolve chlorine at the anode and hydrogen at the cathode. Also disclosed is the addition of a compound of an electrolytic hydrogen evolution catalyzing transition metal to the catholyte liquor while passing electrical current from the anode to the cathode. The addition of the compound of the transition metal through the catholyte liquor causes a reduction in the cell voltage.

    摘要: 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.

    摘要: Disclosed is an electrode having an electroconductive substrate and an electroconductive layer on the substrate. The electroconductive layer is an intermetallic compound of a platinum group metal and a transition metal. Also disclosed is a method of electrolyzing brine, such as sodium chloride brine, where the brine is fed to an electrolytic cell having an anode and a cathode, an electrical current is passed from the anode to the cathode, and chlorine is evolved at the anode, which anode has an electroconductive substrate with an electroconductive layer thereon formed by an intermetallic compound of a platinum group metal and a transition metal. The electroconductive layer may either be an intermediate layer with a further layer of a catalytic material, as an electrocatalytic material or surface catalytic material, or it may be the catalytic material itself.
