Title
(EN) IMPROVED METHOD FOR PRODUCING COBALT METAL POWDER
(FR) PROCEDE AMELIORE DE PRODUCTION D"UNE POUDRE DE COBALT METALLIQUE
Abstract
(EN) Fine particle size cobalt metal powder is prepared by treating an aqueous solution of a soluble cobaltic ammine halide with a sufficient amount of a soluble metallic hydroxide to form a cobalt containing precipitate. The precipitate is separated from the solution and reduced in a reducing atmosphere to produce metallic cobalt.
(FR) Une poudre de cobalt metallique de fines particules est preparee en traitant une solution aqueuse d"un halogenure d"amine cobaltique soluble avec une quantite suffisante d"un hydroxyde metallique soluble pour former un precipite contenant du cobalt. Le precipite est separe de la solution puis reduit dans une atmosphere reductrice pour produire du cobalt metallique.
