AI Technical Summary
Technical Problem
In the existing technology, zirconium silicate has poor dispersion in glazes, which affects the whiteness and gloss of the glaze surface.
Method used
Phytic acid-based polyethylene glycol is used as a dispersant and ball-milled with zirconium silicate. It is then mixed with other components, sprayed with glaze, and fired to form a ceramic glaze with high gloss and high whiteness.
Benefits of technology
It significantly improves the gloss and whiteness of the glaze, achieving a milky white glaze surface, and is suitable for ceramic sanitary ware products.

Abstract
This invention relates to the field of ceramic technology and discloses a high-gloss, high-whiteness ceramic glaze and its preparation method. The high-gloss, high-whiteness ceramic glaze of this invention, by weight, comprises 35-40 parts calcite, 38-45 parts wollastonite, 0.6-1.4 parts potassium feldspar, 0.3-0.8 parts calcined kaolin, 0.6-1.3 parts clay, 1.2-2.8 parts calcined zinc oxide, and 4-16 parts highly dispersed zirconium silicate powder, etc. Phytic acid-based polyethylene glycol contains hydroxyl groups and a large number of sodium phosphate groups, which can improve the interaction between the polyethylene glycol molecular chains and the surface of zirconium silicate powder, effectively achieving surface modification and alteration of zirconium silicate powder. This helps overcome the agglomeration of zirconium silicate and ensures uniform dispersion in the ceramic glaze matrix, significantly improving the gloss and whiteness of the glaze surface.
