A PROCESS FOR MAKING COBALT METAL POWDER |
摘要 |
Dense cobalt powder having coarse, relatively uniformly sized particles can be produced by reducing a cobalt sulphate solution with hydrogen under a partial hydrogen pressure of at least 1 megapascal and at a temperature of at least 180 DEG C. The sulphuric acid generated during the reduction must be neutralised by feeding an alkali metal hydroxide or ammonium hydroxide into the reaction mixture at a rate that does not substantially exceed the molar equivalent of the rate of sulphuric acid production. |
