Embodiment Construction

[0029] The present invention will be further described below through specific embodiments.

[0030] A kind of jade white porcelain prepared by using modified Jiefu kaolin, including a ceramic body, the raw materials of the ceramic body are as follows: 30-40 parts of modified Jiefu kaolin, 10-20 parts of Dehua kaolin, 20 parts of quartz -30 parts, 10-15 parts of montmorillonite, 10-15 parts of potassium feldspar, 10-15 parts of high-temperature frit, 1-5 parts of tricalcium phosphate;

[0031] Among them, the index requirements of modified Jiefu kaolin in terms of mass content are as follows: SiO 2 62%-65%, Al 2 o 3 11%-13%, Fe 2 o 3 1.3%-1.6%, CaO 0.5%-2%, K 2 O 1.8%-1.5%, Na 2 O 0.8%-1.1%;

[0032] According to the mass percentage of the high-temperature frit, the raw material components are as follows: 16.9% kaolin, 12.6% feldspar, 24.5% red lead, 6.8% limestone, 2.6% barium carbonate, 9.8% sodium carbonate, 18.2% zircon, 8.6% boric acid;

[0033] Preferably, the p...

Abstract

The invention relates to the technical field of ceramic manufacturing, and concretely relates to a jade-white porcelain prepared from modified Jiefu kaolin, and a preparation process thereof. The jade-white porcelain prepared from the modified Jiefu kaolin comprises a ceramic green body, and the ceramic green body is prepared from the modified Jiefu kaolin, Dehua kaolin, quartz, montmorillonite, potassium feldspar, high-temperature frit and tricalcium phosphate. According to the jade-white porcelain prepared from the modified Jiefu kaolin, the modified Jiaofu kaolin is introduced as a raw material, the problems that Dehua kaolin is soft, low in iron content and high in potassium content are solved, the prepared jade-white porcelain is high in cleanliness, flawless, fine, pure, free of glazing and fine in body, the jade-white porcelain can meet the manufacturing requirements of art ceramics and daily ceramics, the production cost of traditional jade-white porcelain is reduced, the low-quality Jiefu kaolin is utilized, and the jade-white porcelain has positive economic benefits and social benefits for promoting the development of Dehua ceramic production areas and the popularizationof the jade-white porcelain.

Description

technical field [0001] The invention relates to the technical field of ceramic manufacturing, in particular to a jade white porcelain prepared by using modified kaolin and a preparation process thereof. Background technique [0002] Dehua kiln series jade white porcelain has the characteristics of good whiteness, high gloss, strong thermal stability, temperature resistance, pressure resistance, wear resistance and corrosion resistance, and also has pure and moist glaze color, high density, and good light transmittance, etc. Physical and chemical characteristics. The excellent performance of Dehua jade white porcelain mainly depends on the high-quality kaolin in Dehua County. According to laboratory tests, there are very few impurities such as iron oxide and titanium oxide in Dehua white glaze and porcelain body, so the glaze color is pure. The luster is smooth, like curd and ivory, and the silicon dioxide, potassium, and sodium contained are relatively high, so there are mo...
