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.
