| Introduction | cobalt tetroxide is a black cubic crystal with a spinel structure. Insoluble in water, almost insoluble in acid, fine powder can slowly dissolve in acid. Oxygen is released from 750 °c in air and is converted to CoO at 900-950 °c. |
| preparation | 1) preparing a doping mixed solution, and mixing the doping element ions into the cobalt salt solution to prepare the doping mixed solution; 2) configuration of hydroxide solution; 3) feeding, the doping mixed solution, hydroxide solution and air are introduced into the reaction device at the same time, and the reaction is continuously stirred for 5-20 hours, preparation of doped spherical cobalt tetroxide suspension solution; 4) filtering, filtering the doped spherical cobalt tetroxide suspension solution to prepare doped spherical cobalt tetroxide semi-finished products; 5) washing and drying, the doped spherical cobalt tetroxide semi-finished product is washed and dried to obtain a finished product doped spherical cobalt tetraoxide. |
| Application | cobalt tetroxide is mainly used for battery materials, magnetic materials, thermistors, etc. It can also be used as a catalyst machine for making enamel, etc, it can also be used for the preparation of cobalt oxide and cobalt salts. |
