High hardness and low temperature reinforced porcelain product and sintering technology thereof

Abstract

The invention provides a high hardness and low temperature reinforced porcelain product. The high hardness and low temperature reinforced porcelain product comprises a green body and an enamel layer applied to the green body, wherein the green body is prepared from the following raw materials in parts by weight: 45 to 55 parts of spodumene, 35 to 45 parts of kaolin, 10 to 18 parts of alumina, 5 to10 parts of zirconia, 3 to 5 parts of ceramic fibers, 1 to 3 parts of sea mud, 0.5 to 1 part of bentonite and 0.5 to 1 part of sodium oxide; the enamel layer is prepared from the following raw materials in parts by weight: 10 to 15 parts of kaolin, 8 to 12 parts of feldspar powder, 8 to 12 parts of talcum powder, 5 to 8 parts of quartz, 3 to 5 parts of magnesium sulfate, 1 to 3 parts of chinastone powder and 0.5 to 1 part of zeolite powder. The firing temperature of the high hardness and low temperature reinforced porcelain product provided by the invention is 1150 to 1250 DEG C; the fired ceramic has the characteristics of bright color, delicate and firm porcelain quality, high hardness, high wear resistance, high thermal stability and high water resistance.

Description

technical field [0001] The invention belongs to the technical field of low-temperature strengthened porcelain products, and in particular relates to a high-hardness low-temperature strengthened porcelain product and its firing process. Background technique [0002] In recent years, ordinary daily-use porcelain in domestic and foreign ceramic markets tends to be saturated. In order to enhance market competitiveness, how to produce high-quality ceramics at a lower cost has become a problem that many ceramic manufacturers attach importance to. The quality of ceramics depends not only on other In addition to the appearance, it also depends on its strength, wear resistance, thermal stability, water resistance and other properties. The performance of ordinary ceramics is closely related to its firing temperature. Generally, the higher the firing temperature, the better the performance of ceramics. , but the cost is high; the firing temperature is low, and the performance of cerami...
