Factory Price Cobalt Oxide for Ceramic Industry Into 25kg Bag Packing

The basic informatio
1.Product introductio
  Cobalt oxide (Co203) is a high-priced oxide of cobalt with a theoretical cobalt content of 71.06%, oxygen content of 28.94% and density of 6.079/cm3.It is a black amorphous powder that forms cobalt oxide (Co304) when heated.Cobalt oxide is a compound that is unstable and impossible to be free.What is commonly referred to as cobalt oxide actually still contains a certain amount of cobalt tetroxide.Co203 is stable only when it is in a hydrated state, and this hydrate will be dehydrated and converted to the intermediate oxide cobalt teoxide (Co304) at 265ºC.Cobalt oxide can be reduced to cobalt tetrooxide (Co304) by H2 at 125ºC, and to CoO at 200ºC, and to cobalt metal at 250ºC.Cobalt oxide is insoluble in water but soluble in acids to form corresponding salts.

2.Use of zinc carbonate

Cobalt oxide is an important transition metal oxide.It is usually used as the main raw material for the production of hard alloy, ultra-heat resistant alloy, insulating material and magnetic material, as well as catalyst and dye in the chemical industry. Its main uses are:

  1.paint additives

In the manufacture of a variety of paint when adding cobalt oxide, the production of paint performance has been improved, especially in the paint plays the role of drying agent, that is, in the use of paint is easy to quickly dry, in order to improve the application rate.This is of great benefit to the rapid construction of paint.

  2.enamel and ceramic pigment

With the addition of cobalt oxide, the enamel material can resist corrosion and improve wear resistance.In all kinds of building materials and daily ceramics, blue pigment or glaze made of cobalt oxide is applied to the ceramic products. After roasting, the bright ceramics are presented, which is more artistic.

  3..Refined petroleum catalysts

Cobalt products have a long history as a catalyst in petroleum refining and play an important role in promoting the development of oil refining.Such as some with metal cobalt and aluminum, iron and other alloy catalysts;The use of cobalt oxide as a petroleum catalyst is also very important to accelerate the role of petroleum refining is indispensable.
