Product Description

Zinc Oxide is one of the most important ceramic chemical raw material flux in ceramic industry, Zinc Oxide is widely used in brick and tile glaze and coarse pottery translucent glaze and process transparent glaze glaze tableware coarse ripening. Especially in building ceramics, wall tiles, glazes and low temperature porcelain glaze, more consumption. Zinc Oxide direct to Zinc Oxide or zinc into the glaze, and use Zinc Oxide in the glaze effect: Zinc Oxide has strong fluxing action in the glaze, glaze expansion coefficient can be reduced, improving the thermal stability of the product, but also can increase the glaze gloss and whiteness, improve the elasticity of glaze. At the same time the expansion of melting range can increase the luster glaze. ZnO is an integral part of architectural ceramics and art ceramics.

Generally speaking, Zinc Oxide is mainly used in the following aspects.
1.: Zinc Oxide used as flux in low temperature frit glaze as flux is used, generally at a dosage of 5% to 10%, in the amount of ordinary low temperature raw glaze is about 5%.
2.. Is used as an opaque agent. Adding Zinc Oxide to the glaze containing Al2O3 can improve the opacity of glaze. Because Zinc Oxide can produce zinc spinel ZnO / Al2O3 crystals with Al2O3. In the opaque glazes containing zinc, Al2O3 can improve the whiteness and turbidity of the glaze. SiO2 can improve the gloss of the glaze. 
3. as a crystallization agent: in the art glaze crystal glaze, Zinc Oxide is an indispensable crystallization agent. When molten glaze is cooled rapidly, it forms a larger crystal pattern, which is very beautiful. In crystalline glaze, the dosage of Zinc Oxide is as high as 20 ~ 30%.
4.used as ceramic pigment: because of its strong fluxing effect, Zinc Oxide can be used as flux, mineralizer and glaze carrier of ceramic pigment
