Ceramic Pigment Industry 99% Nanometer Powder Cobalt Oxide CAS 1307-96-6

Cobalt oxide, with the chemical formula CoO, is a metal oxide that is a black gray hexagonal crystal powder that is insoluble in water, alcohol, and ammonia. It is easily reduced to metallic cobalt by carbon monoxide and can react with silicon dioxide, aluminum oxide, or zinc oxide at high temperatures to produce various pigments.

 Cobalt Tetroxide is similar to ferroferric oxide, and can be approximately regarded as a compound formed by cobalt oxide (CoO) and cobalt oxide (Co2O3). Black or grayish black powder. The apparent density is 0.5-1.5g/cm3, and the tap density is 2.0-3.0g/cm3. Cobalt Tetroxide can be slowly dissolved in hot sulfuric acid, but it is insoluble in water, n itric acid and h ydrochloric acid at room temperature. When heated above 1200 ºC, it will decompose into cobaltous oxide. When it is strongly heated to 900ºC in a hydrogen flame, it is reduced to metal cobalt.

Mainly used for glass, enamel, ceramic, magnetic materials such as dense agent, azure blue, cobalt blue, cobalt green color colorant, catalyst, livestock nutrition agent. It is also used in the preparation of cobalt salts.

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.
