Intro：
Strong flux of zinc oxide in the glaze can reduce the coefficient of expansion of the glaze to enhance the thermal stability of the product, while increasing luster and whiteness of the glaze glaze strong. To increase at the same time expand the melting range of the glaze luster.

Uses：
Advanced ceramic zinc oxide is an important ceramic chemical flux materials in the building ceramic wall and floor tile glaze with low-temperature enamel material usage more. Also widely used in the art of glaze in ceramics, zinc oxide is widely used as transparent rough glaze translucent glaze of the tile glaze and crude pottery and craft cutlery dish or cooked glaze. Strong flux of zinc oxide in the glaze, to reduce the expansion coefficient of the glaze, to improve the thermal stability of the product, at the same time to increase the luster and whiteness of the glaze, improve the elasticity of the glaze. To increase at the same time expand the melting range of the glaze luster.
