The ceramic grade Zinc oxide is suitable for manufacturing ceramic pigment, producing ceramic glaze and firing frits. Such zinc oxide can also be used in the production of high-grade glass products.
 
The zinc oxide of Gaoyi Yongchang Zinc Industry has low expansion coefficient, and creates good thermal and mechanical vibration effect when used in the production of ceramic products.


The large specific surface area and strong covering power soundly resolve the issue about the impact of the base color on the surface color of the ceramic products.


The little content of iron makes the ceramic products have small color difference and sound degree of finish when it is used as colored glaze raw materials.
