Cobalt oxide is an important transition metal oxide. Usually as a production of carbide, superalloys, insulation materials and magnetic materials as well as the main raw material in the chemical industry catalysts and dyes. The main application areas of cobalt oxide product is currently as follows:
A paint additive
Cobalt oxide is added in the manufacture of various paints, paint production improved performance, particularly the role played driers in the paint, fast drying paint that is easy to use in order to improve the application rate. This is a great benefit for rapid construction paint.
2, enamel and ceramic pigments
After adding cobalt oxide ceramic material, resistant to corrosion and improve durability. In a variety of building materials and household ceramics, made with blue cobalt oxide pigment or glaze applied to ceramic products by firing after showing a bright ceramic products, more artistic.
3, refined petroleum catalysts
Cobalt products as a catalyst in petroleum refining has a long history and plays an important role in promoting the development of oil refining. If aluminum metal cobalt, iron alloyed catalyst; oil and cobalt oxide as a catalyst is very important role in accelerating the petroleum refining is indispensable. Therefore, the use of cobalt oxide catalyst leapt in recent years an important position.
4, the battery industry
Since the eighties, cobalt powder as a high-energy battery charge and discharge activator, a large number of used rechargeable batteries in the field. Early nineties, Japan, Germany and other countries of Asia scientists successfully added cobalt raw materials to the battery, the battery industry to become high-value research and development, high-tech products. Cobalt powder and cobalt powder, cobalt oxide compounds Asia as a battery material with excellent performance additives to improve Ni (OH) 2 proton conductivity, lower oxidation potential, improve oxygen evolution potential, to improve electrode performance has a significant effect. Can guarantee the charging electrodes are sufficiently pre-charged, so that Ni (OH) 2 converted to full NiOOH, while oxygen-containing precipitate to improve the charging efficiency increase ratio of the electrode capacity. In recent years, with the development of lithium-ion batteries, lithium cobalt oxide as the starting material for preparing ion battery electrode materials, but also to increasing consumption. Our lithium cobalt oxide production in recent years, rapid development, and thus the demand for Co304 correspondingly increased rapidly. Co304 battery grade lithium ion battery cathode material of lithium cobalt oxide main raw material, but also with the lithium ion secondary battery demand increases. In 2002 the total global consumption of cobalt 88 million pounds, the share of drilling applications in the battery industry increased rapidly to reach 32%. With the further growth of small discrete mobile power needs, such as the rapid development of mobile communication and the rapid growth of laptop penetration for the development of lithium-ion battery industry has created better opportunities, correspondingly, the lithium-ion battery demand for cathode materials LiCo02 also increased significantly. 2015 Cobalt applications will reach 230 million pounds, of which 56% will be applied in the lithium battery industry.
5, other raw materials
As with hydrogen peroxide at a temperature reduction of metal cobalt powder and cobalt production, for the manufacture of cemented carbide; dissolved with an acid to an aqueous solution of cobalt, cobalt ingot for electrolysis, a high-temperature high-strength alloy additives; cobalt oxide will be formed acidic cobalt solution, after various chemical processing to produce a cobalt salt, such as CoC2, CoS04, CoCo3 and CoC204 like. Thus, the pure cobalt oxide as an intermediate raw material, widely used. In addition, cobalt oxide phosphors used in the electrical industry as additives and other chemical aspects of the rapidly evolving. Overall, applications of cobalt oxide will continue to develop expanded.
Used: varistors, thermistors, MOA, Picture Tubes, lithium-ion battery industry. Used in making paint pigments, ceramic glazes and cobalt catalysts.
