Abstract

The invention belongs to the technical field of domestic ceramics, and particularly relates to a high-hardness domestic ceramic and a preparation process thereof. The high-hardness domestic ceramic comprises a domestic ceramic green body and a glaze layer, and the glaze layer is prepared from the following raw materials in parts by weight: 35-45 parts of kaolin, 5-10 parts of vein quartz, 3-7 parts of nepheline syenite, 3-7 parts of baddeleyite, 1-3 parts of silicon carbide fibers, 2-4 parts of zirconium oxide fibers, 3-7 parts of boron carbide fibers, 4-8 parts of carboxymethyl cellulose, 2-6 parts of sodium silicate and 25-35 parts of water. Through mutual cooperation of the components and a special heat treatment process, the prepared high-hardness domestic ceramic has relatively high hardness and bending strength.

Description

technical field [0001] The invention belongs to the technical field of daily-use ceramics. More specifically, it relates to a high-hardness daily-use ceramic and its preparation process. Background technique [0002] Daily-use ceramics are produced because of people's daily needs, such as tableware, tea sets, coffee sets, etc., because of their high use value such as high mechanical strength, good thermal stability, and strong chemical corrosion resistance, they occupy an important position in the market. With the improvement of human living standards, there is a greater demand for the hardness of daily-use ceramics. How to improve the quality of daily-use porcelain glazes is an urgent problem to be solved. [0003] CN111138168A discloses a high-hardness glazed daily-use ceramic prepared by introducing graphene and its manufacturing process. The high-hardness glazed daily-use ceramics prepared by introducing graphene include a high-hardness glazed layer, and the raw materi...
