| titleOfInvention | Prepare the method for the ball-shape nickel hydroxide of coated gamma hydroxy cobalt oxide |
| abstract | The invention provides a kind of method preparing the ball-shape nickel hydroxide of coated gamma hydroxy cobalt oxide, first the ball-shape nickel hydroxide of Surface coating cobaltous hydroxide is prepared, again in reactor, under agitation condition, pass into oxygen, in preoxidation to reactor, material color stops change, and it is 40 ~ 150 DEG C that reactor temperature controls; In reactor, add alkali hydroxide soln more afterwards, under agitation condition, continue to pass into oxygen, after oxidizing reaction certain hour, then will the product pure water obtained be oxidized---dry, obtain the nickel hydroxide of coated gamma hydroxy cobalt oxide.Adopt preparation method of the present invention can the cobalt solubilizing reaction at inhibited oxidation initial stage, in preparation process, do not occur the generation of large water gaging, material screen overflow when sieving be less. |
