Usage:(2)Zinc Oxide can well assist enamels’ meltings, and can lower the glazing’s expanding quotiety, and improve the stability in high temperature, meanwhile, it can make the glazing more polishing and more flexible, in a word, improving the luster while enlarging the melting extension. Mainly used in making cobalt glazing (blue), and ceramics pigments, etc., also, ZnO is widely used in the industries of rubber, pharmacy, electronics, etc.
