Top-notch Zinc oxide grade manufacturers in Taiwan.
Taiwan zinc oxide grade manufacturers.
Zinc Oxide Grade-AY is the calcined zinc oxide, also named Special Zinc Oxide. It is calcined at a high temperature of 1200℃ in a special equipment by a special process. The product is superior in quality and of high purity since the volatile matter contained in common zinc oxide has been burnt out. Zinc Oxide Grade-AY is a white or ivory yellowish powder, insoluble in water, but soluble in HCL.
- The product tends to protect the rubber by its opaqueness to ultraviolet light and by its high thermal conductivity.
- Zinc Oxide Grade-AY is a rather refractory oxide, melting at about 1975℃ , and yet when used in moderate amounts in ceramic products, it acts as a flux, decreasing the softening temperature of the product, lowering its viscosity and increasing the maturing range.
-It enhances high brilliance and luster of glass, glazes and enamels. It contributes to the fusibility and helps to control expansion, thus increasing elasticity and resistance to thermal and mechanical shock.
- In ceramic and pottery industry, it reduces the coefficient of thermal expansion, thus increasing the quality of products, improving resistance to oxidation and imparting high stability against deformation under stress.
