Cobalt oxide is an important transition metal oxide. It is usually used as the main raw material for the production of cemented carbide, superalloy, insulating materials and magnetic materials, as well as catalysts and dyes in the chemical industry. At present, the main application fields of cobalt oxide products in my country are as follows:
paint additives
When cobalt oxide is added in the manufacture of various paints, the performance of the produced paints has been improved, especially in the paints, it acts as a drier, that is, it is easy to dry quickly during the use of paints, so as to improve the application rate. This is great for quick application of paint.
Enamel and Ceramic Pigments
After adding cobalt oxide to the enamel material, it can resist corrosion and improve wear resistance. In various building materials and daily-use ceramics, blue pigments or glazes made of cobalt oxide are used to coat ceramic products. After firing, they present bright ceramic products and are more artistic.
Refined Petroleum Catalyst
Cobalt products have a long history as catalysts in petroleum refining, and play an important role in promoting the development of petroleum refining. For example, some alloy catalysts are made of metal cobalt, aluminum, iron, etc.; and the use of cobalt oxide as a petroleum catalyst is also very important, and it is indispensable for accelerating petroleum refining. Therefore, the use of cobalt oxide catalysts has jumped to an important position in recent years.
battery industry
Since the 1980s, cobalt powder has been widely used in the field of rechargeable batteries as an activator for charging and discharging high-energy batteries. In the early 1990s, scientists from Japan, Germany and other countries successfully added sub-cobalt material to battery raw materials, making it a high-value, high-tech product for research and development in the battery industry. Cobalt compounds such as cobalt powder and cobalt oxide powder, as a kind of excellent battery material additives, can improve the proton conductance of Ni(OH)2, reduce the oxidation potential, increase the oxygen evolution potential, and have a significant effect on improving the electrode performance. In the early stage of charging, it can ensure that the electrode is fully charged, so that Ni(OH)2 can be fully converted into NiOOH, and at the same time, the precipitation of oxygen can be suppressed, the charging efficiency can be improved, and the specific capacity of the electrode can be increased. With the development of lithium-ion batteries, cobalt oxide is used as a raw material for preparing electrode materials for lithium-ion batteries, and its consumption is also increasing. my country's lithium cobalt oxide production has developed rapidly in recent years, so the demand for Co3O4 has also increased rapidly. Battery-grade Co3O4, as the main raw material of lithium cobalt oxide, a cathode material for lithium-ion batteries, also increases with the increase in demand for lithium-ion secondary batteries.
Other product raw materials
For example, using hydrogen to reduce cobalt oxide at a certain temperature to produce metal cobalt powder, which is used to make cemented carbide; using acid to dissolve cobalt oxide to make an aqueous solution for electrolysis to obtain metal cobalt ingots as an additive for high-temperature and high-strength alloy steel; Acidic cobalt solution, after different chemical processing can produce cobalt salts, such as CoC2, CoSO4, CoCo3 and CoC2O4, etc. Therefore, pure cobalt oxide is widely used as an intermediate raw material. In addition, the use of cobalt oxide in the electrical industry such as additives for phosphors and other chemical industries has also developed rapidly. In general, the application fields of cobalt oxide will continue to expand.
Applications: Varistors, Thermistors, Zinc Oxide Arrester, Picture Tube Glass, Lithium Ion Batteries and other industries. It is used to make paint pigments, ceramic glazes and cobalt catalysts.
