Introduction: Cobalt tetroxide is a black cubic crystal with spinel structure. Insoluble in water, almost insoluble in acid, micropowder can slowly dissolve in acid. Oxygen is released from 750 ° C in the air and converted into CoO at 900 ~ 950 ° C.

Preparation: 

1) Prepare the doped mixed solution, and mix the doped element ions into the cobalt salt solution to form the doped mixed solution; 

2) Configure hydroxide solution; 

3) Feeding, the doping mixed solution, hydroxide solution and air are simultaneously passed into the reaction device, and continuously stirred to react for 5-20 hours to prepare a doped spherical cobalt tetroxide suspended solution; 

4) filtration, the doping spherical cobalt tetroxide suspension solution is filtered to prepare doped spherical cobalt tetroxide semi-finished product; 

5) Washing and drying, the doped spherical cobaltous tetroxide semi-finished product is washed and dried to obtain the finished product doped spherical cobaltous tetroxide.

Chemical properties: 

cobalt trioxide, chemical formula Co3O4. Molecular weight 240.80. Black powder or gray cubic crystal. The relative density of 6.07, heating to 900 ~ 950℃ to lose oxygen to produce cobalt oxide. Exposure to air absorbs water, but does not produce hydration. Insoluble in water, slightly soluble in nitric acid and release oxygen, soluble in hydrochloric acid and release chlorine, soluble in sulfuric acid. Dissolve in a sodium hydroxide melt or boiling solution to form a blue solution that absorbs a lot of oxygen but does not produce cobalt trioxide. It is hygroscopic. It is easily reduced to cobalt metal by carbon, carbon monoxide or hydrogen. Used for making cobalt metal, cobalt catalyst, enamel, ceramic pigment, semiconductor, grinding wheel and cobalt salt and used as oxidant. Main features: The particle size is uniform, the particle is a complete ball, and the dispersion is good. Scope of application: varistor, thermistor, zinc oxide arrester, picture tube glass, lithium ion battery and other industries.
