Problems solved by technology

However, compared with traditional high-temperature porcelain, bone china also has its disadvantages. First, the hardness of the carcass is relatively poor, and it is easy to produce gaps in the porcelain mouth when the product is used for a long time; second, the thermal stability is relatively poor. , the product is prone to bursting and the service life is low, which needs further improvement

preparation example Construction

[0022] A preparation method of underglaze color bone china includes the following steps:

[0023] (1) Weigh the ingredients according to the raw material formula of the body and the glaze, and the raw materials are separately mixed, crushed, mixed, and wet-milled to prepare the slurry and the glaze;

[0024] (2) The slurry and glaze prepared in step (1) are subjected to a magnetic separator to remove iron for many times until the iron content in the slurry and glaze is less than 0.05%;

[0025] (3) The green slurry obtained in step (2) is made into a green body, which is put into a kiln and sintered at 1220-1260°C for 4-5 hours to obtain a ceramic green body;

[0026] (4) Apply the glaze produced in step (2) to the surface of the ceramic green body obtained in step (3);

[0027] (5) After the glaze on the surface of the ceramic green body is dried, it is put into the kiln, and it is fired in a reducing atmosphere at 760-800℃ for 3-4h, then it is changed to an oxidizing atmosphere, and t...

Abstract

The invention discloses a preparation method of underglaze color bone ash porcelain. The bone ash porcelain comprises a bone ash porcelain green body and glaze; the green body is prepared from the following raw materials in parts by weight: bone black, anorthite, quartz, kaolin, sepiolite, sillimanite, vermiculite, diatomaceous earth, alumina and magnesia. The green body takes bone charcoal, anorthite, quartz and kaolin as main raw materials, supplemented by sepiolite, sillimanite, vermiculite and diatomaceous earth, so that the prepared bone ash porcelain has higher strength; sepiolite with higher thermal stability, sillimanite with higher compressive strength and diatomaceous earth with higher impact strength, tensile strength and tear strength cooperate with bone black, anorthite, quartz and kaolin, so that the finally prepared bone ash porcelain has high compressive strength and impact strength for use as a daily porcelain.

Description

Technical field [0001] The invention belongs to the field of porcelain preparation, and specifically relates to a preparation method of underglaze color bone ashes porcelain. Background technique [0002] Bone china is a high-end porcelain produced in the United Kingdom with a history of more than 260 years. Because of its "thin paper, transparent like a mirror, sound like a chime, and white like jade", the porcelain is delicate and transparent, the shape is beautiful and elegant, the color surface is moist and bright, and the flower surface is colorful.
