High-performance white porcelain body and preparation method thereof

Abstract

The invention relates to a ceramic whiteware body and a preparation method thereof and belongs to the technical field of daily ceramic. The ceramic whiteware body is prepared from a body base materialand body additives, wherein the body material comprises raw materials as follows: Dehua feldspar, albite, Longyan kaolin, fused quartz, Dehua halloysite, lithium China stone and black talc; the bodyadditives comprise a tackifying transparent agent and a toughening enhancer, the addition amount of the tackifying transparent agent is 8-9wt% of the total mass of the body base material, and the addition amount of the toughening enhancer is 12-16wt% of the total mass of the body base material. The production materials of the ceramic whiteware body are easy to obtain, the firing temperature rangeis wider, and the body has better strength and deformation resistance.

Description

Technical field [0001] The invention belongs to the technical field of daily ceramics, and specifically relates to a high-performance white porcelain body and a preparation method thereof. Background technique [0002] Dehua is one of the three ancient porcelain capitals in China, and is as famous as Jingdezhen in Jiangxi and Liling in Hunan. Dehua Kiln is a famous porcelain kiln in the south of ancient China, named after its site in Dehua County. "BLANC DE CHI NE" (BLANC DE CHI NE) is the French praise of Dehua white porcelain in the Ming Dynasty. They think it is "the top grade of Chinese porcelain". Dehua white porcelain is known as "ivory white", "lard white" and "goose down white" due to its fine production, dense texture, crystal-like jade, and moisturizing glaze. It is in the white porcelain system of my country With a unique style, it occupies an important position in the history of ceramics development, and has a reputation of "Oriental Art" in the world.

AI Technical Summary

Problems solved by technology

Since the production process needs to be fired at about 1330°C, the amount of potassium sodium oxide, a single low-temperature flux, in the billet is large, reaching more than 7%, so that the billet is sintered in advance at a lower eutectic point temperature, but this method has the following technologies Defect: There is no liquid phase formation before the green body is close to the lowest eutectic point, but once it reaches the lowest eutectic point temperature, a large amount of liquid phase suddenly appears, and the amount of liquid phase increases rapidly with the increase of temperature, resulting in rapid deformation of the porcelain body

In the prior art, the firing temperature range is only about 10°C, the product is easily deformed and brittle, the flexural strength is about 60MPa, the whiteness is about 76, and the thermal stability is 160-20°C, so it is difficult to guarantee the product during the production process. various performance indicators

[0004] In the production of daily-use ceramics industry, low strength and high deformation rate are the biggest production defects, which affect product competitiveness
