Applications :
The direct method is used in ceramics without high purity , impurity more, the price is certainly cheaper . Of course , high-grade ceramic is best to use the indirect method . Now we come to understand zinc in the glazing of the role and purpose : Zinc oxide has a strong fluxing action in the glaze , the glaze can reduce the coefficient of expansion , improve the thermal stability of the product to increase and improve elasticity glazed gloss glaze .
