AI Technical Summary

Technical Problem

In the existing ceramic glaze preparation process, the matte glaze surface is rough and the ball milling time is long, resulting in high glaze slurry temperature, large thixotropy, and prone to pit problems.

Method used

Using low melting temperature matte frit and appropriate additives, through crushing and ball milling, the melting temperature of the glaze is reduced, the firing range is broadened, the glaze texture is improved, and the glaze slurry temperature is controlled through sieving and spray water cooling. , reduce thixotropy.

Benefits of technology

It achieves a delicate matte effect, reduces ball milling time and temperature, improves glaze slurry performance, and reduces glazing defects.

Abstract

The invention discloses a matte glaze and a preparation method thereof. The matte glaze comprises the following components by weight: 1-5 parts of zinc oxide, 5-15 parts of barium carbonate, 0-15 parts of zirconium silicate, 10-25 parts of potassium feldspar, 10-20 parts of kaolin, 5-15 parts of calcite, 5-15 parts of calcined talcum powder, 20-35 parts of a matte frit and 0.5-1 part of an additive. Specifically, the matte frit comprises the following components by weight: 30-50 parts of SiO2, 15-20 parts of Al2O3, 0.01-0.5 part of Fe2O3, 3-10 parts of CaO, 0.5-5 parts of MgO, 1-5 parts of K2O, 3-10 parts of Na2O, 3-10 parts of ZnO, 0.1-1 part of B2O3 and 10-25 parts of BaO. By introducing the matte frit, the melting temperature of the formula is lowered, the firing range of the formula isbroadened, and the glaze texture achieves a fine matte effect.
