product description
Cobalt oxide (Co203) is an expensive cobalt oxide with a theoretical cobalt content of 71.06%, an oxygen content of 28.94%, and a density of 6.079/cm3. It is a black amorphous powder that generates cobalt oxide (Co304) after heating. Cobalt oxide is an unstable compound and cannot be freed. The cobalt oxide commonly referred to actually still contains a certain amount of cobalt tetraoxide. Co203 is only stable in a hydrated state. This hydrate will dehydrate and transform into the intermediate oxide cobalt tetraoxide (Co304) at 265°C. Cobalt oxide is reduced to cobalt tetraoxide (Co304) by H2 at 125°C, reduced to CoO at 200°C, and reduced to cobalt metal at 250°C. Cobalt oxide is insoluble in water. After dissolving in water, it decomposes into hydrates when it encounters water. It is insoluble in water, but soluble in acid and forms corresponding salts.
Cobalt oxide is an important transition metal oxide. In the chemical industry, it is usually used as the main raw material for the production of hard alloys, super heat-resistant alloys, insulating materials and magnetic materials. It can also be used as a catalyst, dye, etc. Its main uses are:
1. Paint additives
Adding cobalt oxide in the manufacture of various paints improves the performance of the produced paints, especially playing the role of a drying agent in paints, that is, the paint is easy to dry quickly when used to increase the utilization rate. This is very beneficial to the rapid construction of paints.
2. Enamel and ceramic pigments
Cobalt oxide is added to enamel materials to resist corrosion and improve wear resistance. In various building materials and daily ceramics, blue pigments or glazes made of cobalt oxide are often applied to ceramic products. After roasting, they present a bright ceramic color and are more artistic.
3. Refined petroleum catalysts
Cobalt products have a long history as catalysts for petroleum refining and have played an important role in promoting the development of petroleum refining. For example, some catalysts made of metal cobalt and alloys of aluminum, iron, etc.; using cobalt oxide as a petroleum catalyst is also very important and is indispensable for accelerating petroleum refining.
