摘要： A cobaltic oxide hydrate is mixed with spent sulfate electrolyte and the slurry is sparged with air to liberate any entrained chloride ions as gaseous chlorine. Thereafter a reducing agent is used to enable dissolution of the cobalt and obtaining of a chloride-free solution from which, after purification, cobalt can be electrowon.

摘要： The invention provides a nickel foam and a method of forming a nickel foam for a nickel containing battery. An open-cell foam structure is placed in a nickel carbonyl gas containing structure. The foam structure is heated to a temperature at which nickel carbonyl decomposes. Nickel from the nickel carbonyl gas decomposes on the foam structure to form a nickel plated foam structure. The nickel plated foam structure is then sintered leaving an open-cell nickel network to form the nickel foam. The open-cells of the nickel foam comprise substantially hollow wires having a substantially uniform transverse cross-section. The nickel foam is further characterized by the conductivity through the nickel foam multiplied by a factor of 3.4 being equal to or greater than the theoretical conductivity of nickel.

摘要： The invention provides a method of producing nickel hydroxide from elemental metal. Elemental nickel is first introduced into an aqueous ammonia or ammonia/ammonium salt solution capable of dissolving nickel. The potential, as measured by a standard calomel electrode, is allowed to reach a negative or reducing level. Oxygen is added to the aqueous solution at a rate that maintains the negative potential to facilitate the conversion of elemental nickel to nickel hydroxide. Nickel hydroxide may be readily precipitated from the aqueous solution.

摘要： A process for producing nickel hydroxide from nickel powders, in which the feed nickel powder is directly converted in an aqueous solution containing nitrate and particulate nickel at least at room temperature and a pH in excess of about 6 into nickel hydroxide of a high density. Nickel powders of high surface area, e.g. 0.4 m.sup.2 /g or higher, typically produced by the thermal decomposition of nickel carbonyl, are particularly suitable as feed materials for this process.

摘要： The invention provides an apparatus for metal plating a substrate. The apparatus includes a chamber adapted to receive metal carbonyl gas. The chamber includes an infrared transparent window. The infrared transparent window has a cooling passage filled with liquid coolant. The liquid coolant has a temperature below which decomposition of the metal carbonyl gas occurs. The liquid coolant prevents decomposition of the metal carbonyl gas on the infrared transparent window. The liquid coolant also is substantially infrared transparent for allowing infrared radiation through the infrared transparent window and cooling passage into the chamber. An infrared radiation source sends infrared radiation into the chamber through the infrared transparent window and cooling passage to heat the substrate to a temperature at which decomposition of the metal carbonyl gas occurs.

摘要： A process for decreasing the crystallinity of nickel hydroxide by generating and supplying large numbers of heteronuclei into the nickel hydroxide producing reaction system. Nickel sulfate and sodium hydroxide are initially forcefully and intimately combined to form a supersaturated solution of heteronuclei. These heteronuclei are introduced into a nickel powder containing slurry wherein nickel hydroxide having a crystallinity FWHM value of greater than about 0.5° is generated.

摘要： The process precipitates additives onto nickel hydroxide seeds in an ammonia solution. Then introducing at least one metallic additive into the aqueous solution creates a slurry having a reducing potential. The additive is selected from the group consisting of aluminum, cadmium, cobalt, indium, iron, manganese and zinc. Introducing oxygen into the additive-containing slurry at a controlled rate maintains the reducing potential of the solution. At least one of the additives dissolves into the aqueous solution in excess of the slurry's solution solubility to precipitate the additive in the form of a hydroxide on the nickel hydroxide seeds.
