| titleOfInvention | A kind of method of hybrid oxidative synthesis spherical cobaltic-cobaltous oxide |
| abstract | The present invention relates to the preparation method of tricobalt tetroxide, especially a kind of method of hybrid oxidative synthesis spherical cobaltic-cobaltous oxide.The mixed aqueous solution of rose vitriol and complexing agent, aqueous sodium hydroxide solution are injected in reactor continuously through delicate flow Controlling System, adopt the electrochemical method adding oxygenant, oxygen and input dc power that reaction mass is generated hydroxy cobalt oxide sphaerocrystal during reaction, and control the temperature of reaction system, pH value and stirring intensity, flow out continuously through reactor overflow port again, through ageing, washing, hot-air seasoning dehydration, obtain spherical cobaltic-cobaltous oxide.The tricobalt tetroxide that the present invention produces, tap density is large, good sphericity, even particle size distribution stable performance, applied range, and has saved production cost greatly.Compared with prior art, present invention process flow process is simple, and reaction is easy to control.Production cost is low, and product application scope is wide, has larger industrial value. |
