Problems solved by technology

For example, the thermal stability does not meet the relevant standards, the dissolution of lead and cadmium does not meet the standards, and the hardness of the glaze surface is poor, which is not resistant to scratches with knives and forks. Therefore, single-layer low-temperature matt reactive glaze (kiln-changing glaze) daily-use stoneware products are in circulation in the market. very few

Abstract

The invention discloses a low-temperature matte reaction glaze and a production method thereof. The glaze is prepared from following raw materials, by weight, 5-25 parts of frit, 15-30 parts of potassium feldspar, 0-8 parts of quartz, 25-40 parts of calcite, 12-25 parts of calcined zinc oxide, 15-25 parts of titanium dioxide, 3-6 parts of kaolin from Guizhou, 5-12 parts of zirconium silicate and 0-30 parts of toners. According to the low-temperature matted reaction glaze and production method thereof, the calcite and the titanium dioxide are used to achieve a low-temperature sub-reaction effect, then the zirconium silicate is used for stabilizing the glaze, thereby ensuring the effects of the glaze, namely, the effects of the low-temperature oxidizing flame matted reaction glaze (transmutation glaze). A single-layer reaction glaze (transmutation glaze) stoneware product prepared from the glaze is suitable for large-scale production conditions at present and can be produced stably. Meanwhile, physical and chemical conditions, such as thermal-stability, dissolving of lead and cadmium, glaze surface hardness and the like, of the stoneware product meet the national household stoneware standard.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a low-temperature matte reactive glaze and a manufacturing method thereof. Background technique [0002] At present, among the color glaze products fired at a medium temperature of 1250-1300 ℃, reactive glaze (also called kiln-changing glaze) products are relatively abundant, especially the porcelain imitating the five famous kilns in ancient times. Especially the reduction flame reaction glaze (single layer) at about 1300 ℃, the reaction changes in various ways, which is almost fake compared with ancient porcelain. [0003] However, due to the congenital nature of the technology of the reactive glaze (kiln-changing glaze) fired by reduction flames, the products of each kiln have certain differences, which is the biggest shortcoming for exporting to foreign countries. It cannot be stably produced in large quantities, and at the same time, the cost is very high. Therefore,...
