Abstract

The invention relates to a formula of body mud of high-glass-phase stoneware and a preparation process of the body mud. The formula comprises the following chemical components by mass percent: 60.0-67.0% of SiO2, 10.0-14.0% of Al2O3, 8.0-12.0% of MgO, 0.5-2.0% of CaO, 1.0-2.5% of K2O, 0.5-2.0% of Na2O, 3.0-5.0% of BaO and 4-6.5% of loss on ignition. The body mud is prepared according to the formula and the high-glass-phase stoneware is prepared through the processes of body preparing, glazing, firing and the like. By constructing phase equilibrium between polycrystalline phases and material phases in the stoneware body material, the stoneware body material is endowed with the process properties of low firing temperature, short firing time, wide range, low shrinkage, high glass phase and light weight and the economic and technical indexes of energy conservation, consumption reduction and efficiency increase. The body mud has application prospects in the production fields such as top-grade household porcelains, art porcelains, heat insulation porcelains and the like.

Description

technical field [0001] The invention relates to a preparation process of a ceramic material, in particular to a formula and a preparation process of a high-vitreous stoneware body clay. Background technique [0002] The ceramic industry is a large energy consumer, and the roasting of products consumes nearly 70% of the energy in the ceramic production process. Therefore, low-temperature fast firing is the most direct and effective technical means for ceramic enterprises to save energy, reduce consumption, and improve economic benefits. At the same time, low-temperature fast firing is also very positive for improving the utilization rate of ceramic kiln equipment, prolonging the life of the kiln, and reducing the loss of kiln furniture and kiln materials. In a word, low-temperature fast firing is an inevitable choice for the ceramic industry to achieve low-carbon development. Since the reform and opening up, my country has made gratifying achievements in low-temperature fast...
