Zinc Oxide Description:

Nature:White powder, density 5.606, melting point 1975 0C, is an amphoteric oxide, insoluble in water or ethanol, soluble in acid-base solution, high temperature yellow, after cooling to restore whiteness

Use:

Chemical industry grade zinc oxide is widely used in products such as zinc stearic acid, zinc bromide, zinc borate, phosphorization fluid etc, but also be used for mixing the electroplating solution.

 

Function and characteristic: 

1. Small granule, even granularity, it is possessed of high dispersing ability. The chemical reaction is fast and completely, the reaction speed is identical.

2. The purity is high. As raw material, the product purity is high and stable. There is little impurity, reduce the impact on main products of other resultants. 

3. The single granularity density and proportion are small. it is difficult to precipitate in the reaction process. 

4. It is pure white color, and has not influenced the result products color after reacting.
