Problems solved by technology

[0003] At present, the main varieties of Dehua white porcelain are tea sets, sculpture porcelain, etc. The firing temperature range of the existing technology is very narrow and only about 10°C. The product is easily deformed and brittle, with a flexural strength of about 60 MPa, a whiteness of about 76, and thermal stability. It is 160-20℃, so it is difficult to guarantee the performance indicators of the product in the production process

Abstract

The invention relates to the technical field of ceramics, and particularly discloses an environment-friendly high-whiteness domestic ceramic product which comprises Dehua kaolin, albite, quartz, zirconium silicate and composite granules. The composite granules are prepared by coating fluorite tailing powder and calcined smithsonite powder with Dehua Longque red soil dispersed slurry, granulating and drying. The fluorite tailings sintered ceramic is high in whiteness, high in strength, good in thermal shock resistance, suitable for domestic ceramics, energy-saving, environment-friendly, large in sintering range and high in yield due to the fact that the fluorite tailings are recycled. Particularly, in the staged heating, oxidizing and firing process, silicon and aluminum in the Dehua longque red soil dispersed slurry react to serve as mullite crystals, the fluorite tailing powder and the calcined smithsonite powder act synergistically to reduce the melting temperature of the red soil silicon and aluminum, continuous curing of the mullite crystals is accelerated, and a compact framework is formed; the breaking strength and the thermal shock resistance of the green body are favorably enhanced.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to an environment-friendly high-whiteness daily-use ceramic product and a preparation process thereof. Background technique [0002] Dehua is one of the three ancient porcelain capitals in China, as famous as Jingdezhen in Jiangxi and Liling in Hunan. Dehua white porcelain has the reputation of "ivory white", "lard white" and "velvet white" because of its fine production, firm texture, crystal clear jade, and glaze like grease. It is in the white porcelain system of our country. It has a unique style, occupies an important position in the history of ceramic development, and has the reputation of "Oriental Art" internationally. [0003] At present, the main varieties of Dehua white porcelain are tea sets, sculpture porcelain, etc. The firing temperature range of the existing technology is very narrow and only about 10°C. The product is easily deformed and brittle, with ...
