AI Technical Summary

Problems solved by technology

The existing ceramic glazes are mainly made of feldspar, quartz and clay raw materials. The opacifying agent of the glaze has mainly gone through processes such as tin oxide, zinc oxide, titanium dioxide, and zirconium silicate. Due to the cost of tin oxide as an opacifying agent Too high, less and less used today

Embodiment 1

[0014] Embodiment 1 prepares white porcelain glaze

[0015] A white porcelain glaze is composed of the following components in parts by weight: 20 parts of potash stone, 15 parts of albite feldspar, 14 parts of quartz, 10 parts of limestone, 5 parts of cooked talc, 0.8 part of zinc oxide, 2 parts of lithium carbonate, 2 parts of barium carbonate, 5 parts of kaolin, 1 part of silicon micropowder, 2 parts of spodumene, 5 parts of zirconium silicate, the mass fraction of silicon dioxide in the described quartz is greater than 99.6%, and the mass fraction of iron oxide is less than 0.004%. The boiled talc is talc powder calcined at a high temperature of 1250° C., and the whiteness of the boiled talc is greater than 90 degrees.

[0016] Put the above-mentioned components of the white porcelain glaze into a wet ball mill, and wet ball mill to obtain the white porcelain glaze.

Abstract

The invention relates to white porcelain glaze. The white porcelain glaze has the advantages that zirconium silicate and zinc oxide according to a proper proportional ratio are used as an opacifier ofthe white porcelain glaze; the production cost of the white porcelain glaze is reduced, the whiteness and opacity of the white porcelain glaze are improved, meanwhile, the viscosity of the white porcelain glaze is effectively decreased, and the white porcelain glaze is conveniently coated to the outer surface of a white porcelain blank; by adding calcined talcum, the opacifying degree of the white porcelain glaze is effectively improved; by adding a proper amount of kaolin, the consistency of glaze slurry is properly increased, the thickness of a glaze layer is proper, the adhesion force of the glaze to the surface of the blank is increased, and the production of glaze crawling is reduced; by adding a proper amount of lithium carbonate, barium carbonate, Gaozhou kaolin, silicon micropowder and spodumene, the luster of the surface of the white porcelain glaze is effectively improved, and the quality of the white porcelain glaze is improved; the white porcelain glaze is obtained by wettype ball milling through a wet type ball mill, the raw materials for preparing the white porcelain glaze can be uniformly mixed and stirred, the slurry with uniform physical and chemical properties can be obtained, and the white porcelain glaze can be conveniently applied.

Description

technical field [0001] The invention relates to the technical field of porcelain production, in particular to a white porcelain glaze. Background technique [0002] Chinese porcelain has a long history and various varieties. In addition to the noble and elegant blue and white and colorful colored porcelain. Simple and elegant white porcelain is also a variety that people love. Although it does not seem to have colorful patterns and bright colors, it shows people the natural beauty in its simplicity. White porcelain generally refers to porcelain with white porcelain body and transparent glaze on the surface. White porcelain has the characteristics of dense and transparent body, high fire rate for glazing and pottery, no water absorption, clear and long rhyme, etc. Because of its white color, which can reflect the color of tea soup, moderate heat transfer and heat preservation performance, colorful colors and different shapes, it can be called a treasure among tea drinking ...
