Detailed Description
Basic properties:
Packaging: 1 kg per bag.
Molecular formula: ZnO molecular weight: 81.39
White or yellowish powder, the specific gravity of 5.5 - 6.5g/cm3, 8m2/g specific
surface area, particle size of 0.15 - 0.7μ m, refractive index of 1.95 to 2.05, at 20
℃/g.℃heat of 0.0915 cards, melting point 1973 ℃, zinc oxide evaporation at 1000 ℃.
Chemical properties of feed grade zinc oxide:
The zinc oxide by carbon, carbon monoxide and hydrogen is reduced at high temperature;
The zinc oxide is amphoteric oxide, slightly soluble or insoluble in water, generates
the corresponding salts react with acids, and alkali reaction of zinc hydroxide ( Zn (
OH ) 2 ) in long time stored in the air, with the carbon dioxide and other acidic gases
produced in the reaction of basic zinc carbonate.
