Abstract

The invention relates to nonluminous glaze. The nonluminous glaze is prepared by adding a proper amount of aluminum powder into slaked talc, quartz and feldspar to generate metal aluminum oxide without glossiness, so that the production cost of the nonluminous glaze can be effectively reduced; the added slaked talc is subjected to high-temperature calcination, so the impurity content is low, the loss on ignition is small and new grain which people do not like is avoided; a proper amount of silicon micropowder is added into the nonluminous glaze, the temperature resistance and the acid and alkali resistance of the glaze layer can be improved and the effect of improving the mechanical strength of the glaze layer is achieved; and the nonluminous glaze is obtained by performing wet ball milling by a wet ball mill, the raw materials for forming the nonluminous glaze are stirred and mixed uniformly, slurry with the physical and chemical properties tending to be uniform and consistent can beobtained, and glazing is fertilized.

Description

technical field

[0001] The invention relates to the technical field of porcelain production, in particular to a dull glaze. Background technique

[0002] Glaze is a thin, colorless or colored glassy layer covering the surface of a ceramic product. It is made by mixing mineral raw materials such as feldspar, quartz, talc, kaolin and chemical raw materials in a certain proportion, grinding them into glaze slurry, applying them on the surface of the green body, and calcining at a certain temperature. It has the characteristics of increasing the mechanical strength, thermal stability and dielectric strength of the product, as well as beautifying the utensils, being easy to wipe and clean, and not being corroded by dust and filth.

[0003] The ceramic industry can be roughly divided into the following types of lead glaze and lead-free glaze according to the product category and use; raw glaze and frit glaze, ceramic tile, tableware, sanitary ceramics and glaze for electric porce...
