Problems solved by technology

Even wares with the same body glaze composition, because of their different positions in the kiln, sometimes have different glaze colors after firing, which is the so-called phenomenon of "different wares in the same kiln". Moreover, there are bubbles in glazed ceramics, and the bubbles are the result of glaze firing. A relatively common phenomenon in ceramics. Over time, glaze color bubbles tend to become dead bubbles, which affects the aesthetics of ceramic art itself and reduces product value.

specific Embodiment 1

[0024] The raw materials of the unglazed high-density crystal porcelain blank are composed of 38 parts by weight of kaolin, 23 parts of high silica, 17 parts of potassium feldspar, 6 parts of albite feldspar, 12 parts of quartz, and 4 parts of Dehua local china clay;

[0025] The chemical composition of kaolin is: aluminum oxide 35.96%, silicon dioxide 48.15%, iron oxide 0.02%, titanium oxide 0.01%, calcium oxide 0.45%, magnesium oxide 0.57%, potassium oxide 2.17%, sodium oxide 0.2%, balance 12.47 %;

[0026] The chemical composition of potassium feldspar is: 10.18% alumina, 80.45% silica, 0.03% iron oxide, 0.03% titanium oxide, 0.21% calcium oxide, 0.05% magnesium oxide, 8.29% potassium oxide, 0.21% sodium oxide, and Amount 0.55%;

[0027] The chemical composition of albite is: 19.47% alumina, 69.28% silica, 0.09% iron oxide, 0.05% titanium oxide, 0.7% calcium oxide, 0.52% magnesium oxide, 0.5% potassium oxide, 8.47% sodium oxide, and Amount 0.92%.

specific Embodiment 2

[0028] The raw materials of the unglazed high-density crystal porcelain blank are composed of 42 parts by weight of kaolin, 24 parts of high silica, 15 parts of potassium feldspar, 7 parts of albite feldspar, 11 parts of quartz, and 1 part of Dehua local china clay;

[0029] The kaolin, potassium feldspar, and albite are selected from the same raw materials as those in Embodiment 1.

specific Embodiment 3

[0030] The raw materials of glazed high-density crystal porcelain blank are composed of 40 parts by weight of kaolin, 28 parts of high silica, 12 parts of potassium feldspar, 5 parts of albite feldspar, 13 parts of quartz, and 2 parts of Dehua local china clay;

[0031] The kaolin, potassium feldspar, and albite are selected from the same raw materials as those in Embodiment 1.

Abstract

The invention relates to the technical field of ceramic production and particularly relates to unglazed high-density bright crystal ceramic and a preparation method thereof. In the unglazed high-density bright crystal ceramic, the blank is prepared from kaolin, high-silicon soil, potassium feldspar, albite, quartz and Dehua local china clay. By improving the blank and firing technology, the prepared bright crystal ceramic has high density and good thermal shock resistance and is safe to use; without glazing, the water absorption is lower than or equal to 0.2, the lead release is lower than 0.1, the cadmium release is lower than 0.1, the whiteness is high, and bubbles are avoided; in the production of the bright crystal ceramic, complicated production processes are saved, the production cost is greatly reduced since the glazing is not needed, the waste of natural resources is effectively avoided, and the product yield is high; the bright crystal ceramic is natural and moist and has the ceramic appeal incomparable for the glazed ceramic; along with the time change, the ceramic product is naturally tarnished, and the beauty and collection value of the ceramic art work are enhanced; and the bright crystal ceramic is particularly suitable for producing high-grade tea set, Buddha and sculptures and brings positive social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of ceramic manufacturing, in particular to an unglazed high-density crystal porcelain and a preparation method thereof. Background technique [0002] In ceramic production, because the glaze is sensitive to the temperature and atmosphere in the kiln, the fired products will have certain differences in glaze color and enamel quality. Even wares with the same body glaze composition, because of their different positions in the kiln, sometimes show different glaze colors after firing, which is the so-called phenomenon of "different wares in the same kiln". Moreover, there are bubbles in glazed ceramics, and the bubbles are the result of glaze firing. It is a relatively common phenomenon in ceramics. Over time, glaze color bubbles tend to become dead bubbles, which affects the beauty of ceramic art itself and reduces the value of products. Contents of the invention [0003] In order to solve the deficiencies o...
