Embodiment Construction

[0037] The present invention will be further described below in conjunction with embodiment.

[0038] The mineral bone meal and the chemical composition of the raw materials used in the examples are shown in Table 1, and the body composition is shown in Table 2.

[0039] The same glaze is applied to the bodies of all the embodiments, and the weight percentages of the glaze ingredients are as follows: frit 95%, Suzhou soil 3%, Shulongyan soil 2%. The chemical weight percentage of the frit is composed of: SiO 2 54.44%, Al 2 o 3 11.56%, Fe 2 o 3 0.01%, TiO 2 0.01%, CaO 3.78%, MgO 1.49%, KNaO 12.27%, Li 2 O 0.35%, BaO 3.67%, B 2 o 3 5.51%, ZnO 3.87%, SrO 3.05%.

[0040] The chemical weight percentage of the glaze is composed of: SiO 2 54.27%, Al 2 o 3 12.86%, Fe 2 o 3 0.01%, TiO 2 0.01%, CaO 3.61%, MgO 1.43%, KNaO 11.73%, Li 2 O 0.33%, BaO 3.49%, B 2 o 3 5.23%, ZnO 3.68%, SrO 2.99%, and the balance is loss on ignition.

[0041] The main production methods are: ...

Abstract

The present invention relates to a mineral bone powder, crystal bone china and a production method of the crystal bone china. The mineral bone powder is synthesized by mineral apatite and dolomite. A crystal bone china green body consists of ingredients in weight percent as follows: 39-46% of mineral bone powder, 25-32% of crystal, 9-15% of potassium feldspar, 12-18% of synthetic clay, 1-5% of nano-activated clay, and 2-6% of spodumene. The production method of the crystal bone china includes the steps of ingredient mixing, molding, biscuiting, glazing and glaze firing; the crystal needs calcination acid treatment; and the product is formed by biscuiting and glaze firing. For the crystal bone china, by reasonable ingredient mixing, mineral bone powder and crystal are adopted as main materials for producing high-grade china, the firing temperature range is wide, the firing control is easy, and the crystal bone china integrates the characteristics of high white degree, good semi-transparency, high mechanical strength and good thermal stability; and the scientific and rational production method which is easy to implement effectively ensures the quality and the qualified rate of the product and is conducive to industrial production.

Description

technical field [0001] The invention relates to mineral bone powder, crystal bone china and a production method, belongs to the technical field of ceramics, and is a new variety of ceramics, or a new kind of porcelain. Background technique [0002] At present, there are only two kinds of bone meal commonly used in ceramic production. One is natural bone meal, that is, various bones of cattle, sheep, pigs, dogs, chickens, etc. The chemical composition of various animal bones is quite different, resulting in fluctuations in the chemical composition of natural bone meal. Therefore, the chemical composition of the ceramic body prepared with natural bone meal is unstable; the other is synthetic bone meal, which has a relatively stable chemical composition, but the firing shrinkage is relatively large, and the dry strength of the ceramic body prepared with artificial bone meal is relatively low. , It is easy to crack during the molding process, and the porcelain body is easy to bu...
