Fine metal powder is produced from a wet cobaltic hydroxide precipitate by contacting the precipitate with steam to convert the precipitate to a cobaltous oxide and reducing the cobaltous oxide to produce a fine cobalt metal powder.
Claims11
A process for producing a fine cobalt metal powder from an aqueous cobaltic ammine chloride solution comprising treating said aqueous cobaltic ammine chloride solution with an alkali metal hydroxide to form a wet cobaltic hydrated precipitate, contacting said wet cobaltic hydrated precipitate with steam at a temperature greater than about 800.degree. C. for sufficient period of time to convert said cobaltic hydrated precipitate to cobaltous oxide and reducing said cobaltous oxide to produce a fine cobalt metal powder.
