Embodiment 1

[0014] A blue and white porcelain material, the formula of the blue and white porcelain material is made of the following raw materials in weight percent: 75.5-83.2% of natural clay; 10-15% of quartz; 2.6-5% of alumina powder; 2-4% of zirconia powder ; Yttrium oxide powder 0.4-0.8%.

[0015] Alumina powder: high temperature insulation material and reinforced composite material, alumina powder has outstanding high temperature resistance.

[0016] Zirconia powder: It has excellent physical and chemical properties such as high hardness, high strength, high toughness, extremely high wear resistance and chemical corrosion resistance.

[0017] Yttrium oxide powder: additive for high temperature and radiation resistance.

[0018] The production method of the present invention is that the natural clay, quartz, alumina powder, zirconia powder and yttrium oxide powder of the above ratio are first mixed by a mixer, then ground by a grinder and granulated by a granulator to make a unifor...

Embodiment 2

[0020] The formula of the blue and white porcelain material includes the following raw materials in weight percent: 78.6% of natural clay; 13% of quartz; 4.6% of aluminum oxide powder; 3.2% of zirconium dioxide powder; and 0.6% of yttrium oxide powder.

[0021] Production method is with embodiment 1.

[0022] Through carrying out scientific statistics to embodiment 1 and 2, it is found that the effect of embodiment 2 is the best, and the fracture defective rate is only 0.45%, greatly reducing the defective rate.

Abstract

The invention relates to the field of porcelain and discloses a blue and white porcelain material. The blue and white porcelain material is prepared by the following raw materials by weight percentage: 75.5-83.2 percent of natural clay, 10 to 15 percent of quartz, 2.6 to 5 percent of aluminium oxide powder, 2 to 4 percent of zirconium dioxide powder, and 0.4 to 0.8 percent of yttrium oxide powder. The blue and white porcelain prepared through the materials provided by the formula of the invention has the characteristics of low friction and high abrasion resistance, the defective percentage due to breakage is greatly lowered, and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of ceramic production, and in particular relates to a blue and white porcelain material. Background technique [0002] Ceramics are materials and various products made of clay as the main raw material and various natural minerals through pulverization, mixing, molding and calcination. People make a kind of pottery clay and fire it at a high temperature in a special kiln called ceramics, which is the general term for pottery and porcelain. The traditional concept of ceramics refers to all artificial industrial products that use inorganic non-metallic minerals such as clay as raw materials. It includes various products made of clay or a mixture containing clay through kneading, shaping, and calcination. It ranges from the roughest earthenware to the finest fine pottery and porcelain. Its main raw material is silicate minerals (such as clay, quartz, etc.) taken from nature, so it belongs to the category of "...
