| titleOfInvention | Preparation method of cobalt carbonate and preparation method of cobalt tetroxide |
| abstract | The invention discloses a preparation method of cobalt carbonate and a preparation method of cobalt tetroxide. The preparation method of cobalt tetroxide includes the following steps: preparing an ammonium bicarbonate solution; preparing a cobalt chloride solution; adding a predetermined amount of deionized water to a reaction vessel, heating the deionized water to a predetermined temperature; adding part of the ammonium bicarbonate solution to a In the reaction vessel, and adjusting the pH of the solution in the reaction vessel to pH 7.1-7.6; adding the cobalt chloride solution and the remaining ammonium bicarbonate solution into the reaction vessel, stirring and reacting to generate cobalt carbonate; adding the solution in the reaction vessel and The cobalt carbonate is filtered to obtain cobalt carbonate; the cobalt carbonate is washed; and the cobalt carbonate is calcined to obtain cobalt tetroxide powder. The preparation method of cobalt tetroxide has the advantages of low raw material price, easy realization, high controllability, and uniform particle size and morphology of the prepared cobalt tetroxide. |
