Abstract

The invention relates to a high-strength and high-whiteness ceramic product and a processing technology thereof. The high-strength and high-whiteness ceramic product comprises the following components in parts by weight: 20-30 parts of tempered glass, 30-40 parts of a nano precursor, 5-8 parts of quartz, 6-8 parts of magnesium oxide, 10-12 parts of a binder, 10-15 parts of bentonite and 18-20 parts of kaolin. The processing technology of the high-strength and high-whiteness ceramic product comprises the following steps: S1, stirring and mixing tempered glass, quartz, magnesium oxide, bentonite and kaolin, carrying out ball milling, and sieving with a 200-mesh sieve to obtain a mixture; s2, adding a binder and a nano precursor into the mixture obtained in the step S1, and continuously stirring to obtain a forming material; and S3, carrying out molding, degumming and sintering on the molded material obtained in the step S2 to obtain the high-strength and high-whiteness ceramic product. The prepared high-strength and high-whiteness ceramic product is high in whiteness, excellent in strength and good in mechanical property.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a high-strength and high-whiteness ceramic product and its processing technology. Background technique [0002] There are also formulas and preparation methods for ceramic products in the prior art. Although the ceramic products prepared according to these formulas and methods have certain gloss, there are problems of low whiteness, low strength or poor toughness of ceramic products, which are difficult to obtain. Realize the characteristics of high whiteness and high strength. For example, some existing ceramic products have low strength and low ceramic bearing capacity. With the development of the economy and the improvement of people's living standards, people have higher and higher requirements for the quality of life. Consumers have continuously improved performance requirements for ceramic handicrafts, not only requiring the products to be beautiful, but also requiring c...
