Welcome to Shandong Huiyuan Zinc Factory
Zinc oxide used in high-grade ceramic glaze materials
1. Characteristics:
Huiyuan brand zinc oxide used by high-grade ceramic glaze materials has fluxing action. It can reduce the coefficient of expansion of glaze and improve the thermal stability of the product. At the same time, it can increase the luster and white degree of glaze, thus improve the strong character of glaze. It can increase the glaze color brilliance while expanding the scope of melting.
2. Usage:
Huiyuan brand zinc oxide used by high-grade ceramic glaze materials is a kind of important ceramic chemical raw material. In construction, ceramic wall ground brick glaze materials and low temperature ceramic glaze materials use more. It is also widely used in art glaze material. In ceramics, zinc oxide is commonly used to make many things, like art tableware, dish, etc.
