Abstract

The invention relates to a red pottery and a preparation process thereof. The red pottery comprises a biscuit, a making-up soil layer and an enamel layer, wherein the preparation raw materials of the biscuit comprise the following components: 17.0-23.0% of aluminium oxide, 60.0-75.0% of silicon oxide, 1.0-1.5% of ferric oxide, 2.0-4.0% of calcium oxide, 1.0-1.5% of magnesium oxide, 1.7-2.0% of potassium oxide, 1.0-3.0% of phosphorus oxide and 2.0-6.0% of ignition loss; and the biscuiting temperature and firing temperature of the red pottery are respectively 1020-1060 DEG C and 1050-1100 DEG C in a preparation process. The red pottery can be used for solving the problems that red pottery products cannot be enameled, are single in decoration, low in grade and the like; and additionally, compared with a conventional pottery, the firing temperature is reduced by about 200 DEG C, so that the firing energy consumption is greatly reduced, the production cost is effectively lowered, and the environmental protection is benefited.

Description

Technical field [0001] The invention relates to a ceramic formula and its preparation process, in particular to a red soil ceramic formula and its preparation process. Background technique [0002] The main raw material of red clay body is rich in red clay resources, good plasticity and easy to shape, and the firing temperature range is from 1000 to 1250°C. However, due to the internal structure of the product materials, it is difficult for red soil pottery to form a stable intermediate layer of glaze. For this reason, most of the red soil pottery products appear in the form of plain color (that is, the surface is decorated with cement paint or organic paint); Such products have rough surface, poor hand feel, and no porcelain smooth and delicate surface, resulting in a situation where the product grade is generally low and the market price is not high, which limits its development space. [0003] In addition, in recent years, due to the increasing emphasis of the international com...
