  • Production of ultrafine cobalt powder from dilute solution
    Patent number: 4093450
    Abstract: A process for producing ultrafine cobalt powder includes providing an aqueous solution of cobalt ammine carbonate, with the concentration of cobalt ions being in the range of from about 1 to about 20 grams per liter (gpl). The solution is heated to drive off ammonia and carbon dioxide and precipitate ultrafine cobalt oxide. The cobalt oxide precipitate is then separated from the solution and heated in a reducing atmosphere to reduce the cobalt oxide to ultrafine cobalt powder.
