Problems solved by technology

The crystallized glaze is greatly affected by the fineness of the glaze, the firing temperature, and the composition of the ceramic body, resulting in inconsistent shapes and sizes of crystal flowers, so that it cannot be mass-produced. The more serious problem is that the crystal form is not controlled. hershey will cause the product to burst

preparation example Construction

[0057] The present invention also provides the preparation method of above-mentioned crystalline glaze, comprises the following steps:

[0058] 1) taking glass powder, zinc oxide, titanium dioxide, and kaolin by weight as raw materials, adding water to grind the glaze slurry;

[0059] 2) Add barite in parts by weight and mix well;

[0060] 3) Apply glaze to the body and fire it.

[0061] Preferably, ball milling is used to grind the glaze slurry. In step 1), the ratio of the raw materials, balls and water is 1:2-5:0.5-2.

[0062] Preferably, in step 2), after barite is added, the concentration of the glaze slurry is 35-50 degrees Baume.

[0063] Preferably, in step 3), the firing process is carried out under an oxidizing atmosphere, the firing temperature is 1200-1300° C., and the firing time is 6-10 hours.

[0064] The present invention also provides a preparation method of the above-mentioned crystalline glaze. Firstly, each raw material except barite is weighed by weight...

Abstract

The invention discloses a crystalline glaze. The crystalline glaze is prepared from the following components in parts by weight: 10-100 parts of glass powder, 1-50 parts of zinc oxide, 1-50 parts of titanium dioxide, 1-30 parts of kaoline and 1-20 parts of barite. The invention further provides a preparation method of the crystalline glaze. According to the invention, the barite is added into thecrystalline glaze, is slowly decomposed under high temperature, and can release small bubbles to obstruct the growth of crystals, so that the shapes and sizes of the crystals can be controlled, and the shapes and sizes of crystal flowers of the fired crystalline glaze tend to be uniform, so that the crystalline glaze is especially suitable for batch production of different batches and whole sets of products; and in addition, the generation of porcelain explosion defects of products can be reduced and the finished product ratio can be increased.

Description

technical field [0001] The present application relates to the technical field of ceramic glazes, in particular to a crystalline glaze and a preparation method thereof. Background technique [0002] Crystalline glaze is a highly decorative artistic glaze, which contains a certain number of visible crystals. Crystalline glaze is made of appropriate formula. During the firing process, the thermodynamic conditions are controlled to cause crystallization and growth in the glaze layer, thereby forming a crystal-decorated glaze layer. The crystallized glaze is greatly affected by the fineness of the glaze, the firing temperature, and the composition of the ceramic body, resulting in inconsistent shapes and sizes of crystal flowers, so that it cannot be mass-produced. The more serious problem is that the crystal form is not controlled. Hershey will cause the product to burst. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the first o...
