Superiority
The direct zinc oxide for the white or the micro yellow spherical attritive powder, density 5.47g/cm3, the melting point 1800 ℃, does not dissolve in the water, dissolves in the acid, the alkali, the ammonium chloride and the ammonia water. Can absorb in the air in the humid air the carbon dioxide production basic zinc carbonate. Its biggest characteristic is the particle size 50-100 nanometers, has in a big way compared to the indirect method zinc oxide and the direct method zinc oxide compared to the surface area, has the high-activity and the good dispersivity in the application.
