Embodiment 1

[0023] The blanks were weighed according to the following weight percentages: 45% bone meal, 5% quartz powder, 4% Mujie soil, 10.8% petalite feldspar, 12.6% Longyan washing mud, 12% Hunan feldspar, and 10.4% alumina.

[0024] Prepare the bone china of this embodiment as follows:

[0025] (1) The ashes are mixed in a ball mill, poured out of the slurry well, repeatedly washed with water, stirred and pressed to obtain a bone cake;

[0026] (2) The total amount of the remaining raw materials other than ashes and bone cake: balls: water are ground in a ball mill for 35 hours at a weight ratio of 1:1.5:1, then mixed in mud wells, sieved, and iron removed;

[0027] (3) After absorbing iron, it is mixed in a mud well, filtered and put into a mixer, and sodium humate is added to form it by grouting;

[0028] (4) After forming, it is dried, bisque fired at 1270°C, glazed, and glaze fired to obtain the finished product.

Embodiment 2

[0030] The blanks were weighed according to the following weight percentages: 42% bone meal, 3% quartz powder, 6% wood section soil, 11.4% lithium petalite feldspar, 12% Longyan washing mud, 13% Hunan feldspar, and 12.4% alumina.

[0031] Prepare the bone china of this embodiment as follows:

[0032] (1) The ashes are mixed in a ball mill, poured out of the slurry well, repeatedly washed with water, stirred and pressed to obtain a bone cake;

[0033] (2) The total amount of the remaining raw materials other than ashes and bone cake: balls: water are ground in a ball mill for 40 hours at a weight ratio of 1:2:1.2, then mixed in a mud well, sieved, and iron removed;

[0034] (3) After absorbing iron, it is mixed in a mud well, filtered and put into a mixer, and sodium silicate is added to form it by grouting;

[0035] (4) After forming, it is dried, biscuit fired at 1290°C, glazed and glaze fired to obtain the finished product.

Embodiment 3

[0037] Weigh the billet according to the following weight percentages: 48% bone meal, 2% quartz powder, 6% wood section soil, 10% lithium petalite, 12% Longyan washing mud, 12% Hunan feldspar, and 10% alumina.

[0038] Prepare the bone china of this embodiment as follows:

[0039] (1) The ashes are mixed in a ball mill, poured out of the slurry well, repeatedly washed with water, stirred and pressed to obtain a bone cake;

[0040] (2) The total amount of the remaining raw materials other than the ashes and the bone cake: balls: water are ground in a ball mill for 30 hours at a weight ratio of 1:1.8:1.1, then mixed in mud wells, sieved, and iron removed;

[0041] (3) After absorbing iron, it is mixed in a mud well, filtered and put into a mixer, and sodium silicate is added to form it by grouting;

[0042] (4) After forming, it is dried, bisque fired at 1280°C, glazed and glaze fired to obtain the finished product.

Abstract

The invention discloses a bone china and a preparation method of the bone china. The bone china is composed of the following components in percentage by weight: 40-50% of bone ash, 2-6% of quartz powder, 2-6% of kibushi clay, 10-15% of petalite, 12-15% of Longyan washing mud, 12-15% of Hunan feldspar, and 10-20% of aluminum oxide. The preparation method of the bone china comprises the steps of: mixing bone ash by a ball mill, pouring slurry into a slurry well, repeatedly washing with water and stirring, and carrying out pressure filtering to obtain a bone cake; and ball-milling the bone cake with the other components, removing iron, injecting slurry and molding, drying, carrying out biscuit firing, glazing, and firing glaze. The obtained bone china has high plasticity, and can be used for preparing 1.5mm thin film china; and the bone china has good heat shock resistance, and does not crack in 180-200 DEG C water.

Description

technical field [0001] The invention belongs to the field of ceramics, and in particular relates to bone china and a preparation method thereof. Background technique [0002] Bone China, also known as bone china, was invented by the British in the late eighteenth century to imitate Chinese porcelain. Its main feature is that ashes are added to the raw materials, and the skeleton is formed by the phosphate in the ashes to obtain a soft porcelain different from ordinary silicate ceramics. [0003] Usually, bone china is fired twice by high-temperature biscuit firing and low-temperature glaze firing to obtain products with high whiteness, good transparency, fine porcelain quality, bright glaze surface, and regular shape. It is recognized as a high-end daily-use porcelain in the world. However, in the composition of bone china production, it has the problem of poor plasticity, so the wall of bone china products on the market is relatively thick, which increases the production c...
