Product Description

Zinc Oxide

1. Molecular formula: Zinc Oxide

2. Purity: 99.5%min

3. CAS: 1314-13-2

4. HS Code: 2817001000
 

5. Melting Point: 1975ºC
    In order to improve the physical properties and chemical composition of raw zinc oxide extracted by zinc steam, such as direct zinc oxide and indirect zinc oxide, on ceramic glaze, heavy zinc oxide was prepared by high temperature processing and calcination.
    Calcined zinc oxide ratio is significant, good fluidity, with its production of glaze shrinkage is small, the glaze is not easy to pinhole and crack. The quality standard of calcined zinc oxide is the same as that of grade zinc oxide except for the ratio.
After calcined at high temperature, zinc oxide shows light yellow and its melting point is 1975ºC.

Applications

1. Used as flux: when ZnO is used as flux in low-temperature frit glaze, the general dosage is between 5% and 10%, and about 5% in low-temperature raw glaze.

2. Used as opacification agent: Zinc oxide was added to glazing with high Al2O3 to improve opacification of glazing. Because ZnO can form zinc spinel crystals with Al2O3. In zinc-containing opacities glazes, Al2O3 can improve the whiteness and opacities of glazes. SiO2 can improve the gloss of the glaze.

3. Used as crystallization agent: in the art glaze crystal glaze, ZnO is indispensable crystallization agent, in the molten
glaze cooling, it forms a large crystal pattern, very beautiful. The amount of ZnO in crystalline glaze is up to 20 ~ 30%.

4. To make cobalt blue glaze: ZnO is a very important flux in cobalt blue glaze, it can make cobalt oxide in the glaze to form a beautiful sky blue.

5. Used as ceramic pigments: because of its strong melting effect, ZnO can be used as a flux of ceramic pigments, mineralizing agent and glaze color carrier. Used as main raw material in brown ceramic color series

6. As a glass additive: add aluminum, gallium and nitrogen zinc oxide transparency up to 90%, can be used as a glass coating, let visible light through at the same time reflect infrared. Paint can be applied on the inside or outside of window glass to achieve the effect of heat preservation or insulation.
