Problems solved by technology

[0004] With the depletion of raw materials such as "big ball clay", it is not realistic to use the past raw material formula to produce high-grade ceramics, and it is not realistic to rely entirely on a little big ball clay raw material collected by people. Moreover, due to the discovery of new high-quality raw materials, the improvement of production and processing technology and equipment More advanced, a new high-grade mud glaze formula suitable for Liling underglaze multicolored porcelain has become possible

Embodiment

[0038] The preparation method of crystal jade porcelain raw materials is as follows:

[0039] (1) The raw materials of Changning kaolin, Longyan washing mud, Qingyuan mud, and large ball mud are processed by wet ball milling (the mass ratio of raw materials, balls and water is 1:2:0.55), and the ball milling until the fineness is 200 mesh Sieve residue is less than 0.3%;

[0040] (2) Remove iron from the above-mentioned ball-milled Changning kaolin, Longyan mud, Qingyuan mud, and large ball mud, press, filter, and dry them for later use;

[0041] (3) The raw material feldspar powder is deironed by wet method, dehydrated and dried for later use;

[0042] (4) The raw materials processed in steps (1) to (3) are 30% of Changning kaolin, 25% of Longyan washing mud, 25% of Qingyuan mud, 5% of clinker, 10% of feldspar powder, and 5% of large ball mud according to the mass percentage. % Weighing, adding to the ball mill, wet ball milling (the mass ratio of raw materials, balls and w...

Abstract

The invention belongs to the field of ceramic and discloses a Jingyu porcelain raw material preparation method. The preparation method utilizes 25-35% by mass of kaolin, 20-30% by mass of Longyan washing mud, 20-30% by mass of Qingyuan mud, 2.5-7.5% by mass of a clinker, 7-13% by mass of feldspar powder and 2.5-7.5% by mass of large plagiopematite weathering residue balls. A Jingyu porcelain finished product prepared from the Jingyu porcelain raw material contains fewer impurities, has a wide sintering temperature range and has whiteness of 88%, transparency of 41% and glossiness of 91.9%.

Description

technical field [0001] The invention belongs to the field of ceramics, and in particular relates to a preparation method of crystal jade porcelain raw materials. Background technique [0002] High-temperature (about 1400°C) feldspar porcelain, as a kind of ceramics, has always been loved by people because of its fine and white porcelain, smooth jade-like glaze, high compressive strength, and good glaze hardness. Liling underglaze porcelain is very particular about the formula of raw materials and production process, and the whiteness, glaze gloss, strength, hardness and light transmittance of porcelain. [0003] In the early 1960s, the Hunan Provincial Institute of Ceramics used a special kaolin (commonly known as: big ball clay) from Huaihua Hongjiang to prepare Liling underglaze multicolored porcelain. Because of its high whiteness and gloss, strong transparency and warm texture, it has been widely praised by the society. [0004] With the depletion of raw materials such...
