Abstract

The invention provides matte glaze and a production process thereof. The matte glaze comprises 25-30 parts of kaolin, 10-16 parts of clay, 8-12 parts of borax, 15-18 parts of matte frit, 5-8 parts ofbentonite, 3-5 parts of aluminum-magnesium hydrotalcite, 2-5 parts of kojic dipalmitate, 3-6 parts of calcium phosphate, 3-5 parts of calcium oxide and 9-12 parts of stannous chloride. The productionprocess includes: grinding, regulating glaze concentration, applying the glaze and performing oxidation firing to obtain a ceramic product with the matte glaze on the surface. The matte glaze producedaccording to the material proportion has the advantages that the glaze can be stably combined with a green body and be solidified into a polycrystalline structure during ceramic firing to achieve a matte effect, and the glaze is moderate in surface tension, smooth and mellow in surface and fine and smooth in texture. The production process is easy in temperature control, short in firing time andlow in production cost.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a matte glaze and a manufacturing process thereof. Background technique [0002] Matte glaze is a special glaze between glossy glaze and matte glaze. Its glaze surface has weak reflective ability and no glassy luster on the surface, but it presents a soft silky or velvet luster. After the glaze material of the matt glaze is melted at high temperature, a part of the glaze components is separated into crystals during the cooling process, and the crystals are extremely small and regularly dispersed and embedded in the glass matrix, and the light source illuminates it to produce diffuse reflection. [0003] In order to ensure that the precipitated crystals of the matt glaze are evenly dispersed in the glass matrix, so that the obtained matt glaze has a uniform and compact texture. However, the glazes of the existing matt glazes generally have complex components, and the ...
