摘要： Calcium hypochlorite compositions that are classified as a Packing Group III Division 5.1 oxidizer material or as a non-Division 5.1 oxidizer material are described. In one embodiment, the compositions comprise an admixture of particulate calcium hypochlorite and particulate metaboric acid. The calcium hypochlorite is present in the composition in an amount and is of a concentration such that the composition would be classified as a Packing Group II Division 5.1 oxidizer in the absence of said particulate metaboric acid. Other embodiments described are solid shaped articles, e.g., tablets, comprising the described calcium hypochlorite-metaboric acid composition.

摘要： A method of forming a liquid-permeable asbestos-free diaphragm on a cathode structure is described. The method comprises forming a liquid-permeable diaphragm base mat comprising fibrous synthetic polymeric material, e.g., polytetrafluoroethylene, on a cathode structure, e.g., a foraminous cathode; drawing a liquid slurry comprising an aqueous medium containing a wetting amount of surfactant and water-insoluble inorganic particulate material through the base mat, thereby to deposit said inorganic particulate material on and within the pre-formed base mat; and drying the resultant diaphragm at temperatures less than the temperature at which decomposition by-products of the surfactant are formed. The liquid slurry is substantially free of alkali metal halide and alkali metal hydroxide; and the inorganic particulate material comprises at least one oxide or silicate of a valve metal, e.g., zirconium oxide, having a median diameter of 0.1 to 5 micrometers, and optionally clay mineral and/or hydrous oxide of zirconium and/or magnesium. In a further embodiment of the present invention, the base mat is dried prior to deposition of the inorganic particulate material.
