Product Description

CAS No.:1314-13-2

EINECS:215-222-5

Molecular Formula:ZnO

Molecular Weight:81.39

Appearance:White or light yellow fine powder, odorless, tasteless, Yellow at high temperature and white after cooling, melting point of 1975℃ (3587F) 

Solubility:It is a two-stage oxide, soluble in acid、concentrated hydroxid、 ammonia water and ammonium salt solutions, difficult to dissolve in water and ethanol。

Uses:

Chemical grade zinc oxide is widely used in the production of zinc stearate, zinc bromide, zinc borate, phosphating liquid and other products.

Characteristic:

1. Small particle size, uniform particle size, strong dispersal ability, fast and thorough chemical reaction speed, and consistent reaction speed.

2. High purity can make products with high purity and high stability. Less impurities greatly reduce the effect of other products on the main products.

3. Small density and specific gravity of single particles make it difficult to precipitate in the reaction process.

4. Pure white color has no effect on the color of the product after reaction.
