White porcelain made of glutinous rice in Dehua and its preparation technology

Abstract

The invention belongs to the field of ceramic products, and particularly relates to Dehua rice grain bodied white porcelain and a preparation method thereof. According to the Dehua rice grain bodied white porcelain, a rice grain rough-body is prepared from kaolin, calcined kaolin, bone meal, Dehua quartz, nanometer aluminum oxide, nanometer cordierite powder, nanometer titanium dioxide and nanometer zirconium oxide. The Dehua rice grain bodied white porcelain is fine and white in body skeleton, pure in body color, extremely good in light transmission, and mild and fine in body. Under the irradiation of strong light, slight faint yellow or jade white are reflected in the white of the porcelain color, and the Dehua rice grain bodied white porcelain has the artistic effect closest to that of traditional Dehua rice grain bodied white porcelain. In the rice grain bodied white porcelain, the quality and the content of the kaolin in the rough-body raw materials are reduced, the high-temperature calcined kaolin is utilized to be cooperated with the bone meal and the Dehua quartz to serve as the base basic raw material, and a proper amount of nanometer compound powder is introduced, so that the body obtained by using the raw materials with the kaolin reduced has the equally good porcelain quality, and the technical problem that the traditional rice grain bodied porcelain is soft in texture so that a large size of porcelain cannot be manufactured is overcome.

Description

technical field [0001] The invention belongs to the field of ceramic products, in particular, the invention relates to a Dehua glutinous rice body white porcelain and a preparation process thereof. Background technique [0002] Dehua white porcelain has always been known for its excellent fetal quality. Dehua white porcelain is made of local kaolin clay. In addition, the pure white glaze with extremely low iron oxide content and extremely high potassium oxide content, and a neutral atmosphere during firing, make the glaze color of Dehua kiln white porcelain appear extraordinarily pure. The existing Dehua white porcelain is more about the similarity in surface and color, but the charm of the real Dehua white porcelain is reflected from the fetus, commonly known as "glutinous rice fetus", the fetal bone is soft and firm, with crystal clear The luster, the color is warm and moist like jade, clear and smooth, the body of the vessel can be reflected in the shadow of fingers unde...

Problems solved by technology

The traditional Dehua white porcelain must use Dehua local kaolin as raw material to realize the glutinous rice body. As a non-renewable resource, Dehua local kaolin has been fully developed, and the stock is scarce and expensive.

[0003] In order to solve the above problems, the invention patent application with the application publication number of CN 106278337 A discloses a kind of high-density mercerized jade porcelain with glutinous rice base and its manufacturing process. , Jiangxi kaolin, Australian kaolin, Dehua local kaolin and other kaolin, the ratio is close to the raw material of traditional Dehua glutinous rice porcelain, the total amount of kaolin is as high as 65-93, as we all know, kaolin has strong plasticity, but its Soft, but after introducing a large amount of kaolin as the raw material of the green body, the green body is easy to soften and deform during firing, which makes it impossible to fire large-scale utensils, and the price of high-quality kaolin is expensive, resulting in high production costs
