Abstract

The present invention discloses a matt glaze and a fabrication process. The matt glaze consists of transparent glaze material, high-expansion glaze material and Suzhou kaolin clay at mass ratio. Each of the transparent glaze material and the high-expansion glaze material consists of silica, alumina oxide, potassium feldspar, albite, calcium carbonate, borax and barium carbonate. The fabrication process comprises the following steps: uniformly mixing the raw materials in proportion, then mixing the mixture with water to stir, and putting the mixture into a ball mill for ball milling so as to prepare matt glaze material; spraying and coating the matt glaze material onto the surface of a ceramic body, feeding into a baking furnace for baking, and obtaining a calcined product with a matt glaze surface effect after cooling from the kiln. The matt glaze provided by the present invention is simple in composition and reasonable in formula, and the prepared matt glaze is stable in glaze surface effect, comfortable in gloss, free of glare, smooth and is high in strength. In the fabrication process, the calcining time is short, and the sintering temperature is low, so that the power consumption is reduced, the energy is saved, the environment is protected, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of glaze preparation, in particular to a matt glaze and a production process. 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 presents a soft silky or velvet luster. After the glaze material of matt glaze is melted at high temperature, crystals are separated out in a part of the glaze components during the cooling process. The crystals are extremely small and regularly dispersed and embedded in the glass matrix, and the light source irradiates on it to produce diffuse reflection. The existing matte glaze has complex components, and the firing time is long, the firing temperature is high, the production requires more fuel, the production efficiency is relatively low, and the production cost is high. Contents of the invention [0003] The purpose of the present invention ...
