High-strength medium-temperature crackle glaze ceramic product and manufacturing method thereof

Abstract

The invention provides a high-strength medium-temperature crackle glaze ceramic product which comprises a body material and glaze, and the body material comprises the following raw materials: kaolin, quartz, potassium feldspar, clay, talc and ceramic micro-powder; and the glaze is prepared from the following raw materials: potassium feldspar, albite, kaolin, dolomite, quartz, barium carbonate, zinc oxide, copper oxide, aluminum oxide, heavy calcium carbonate and plant ash. The manufacturing method of the high-strength medium-temperature cracked glaze ceramic product comprises the following steps: respectively mixing a body material and a glaze material, adding water, performing wet milling by using a ball mill, and sieving to obtain body material slurry and glaze slurry; preparing blank biscuit firing from the blank slurry; glazing; and sintering. The ceramic product prepared by medium-temperature firing is short in firing time and low in temperature, so that the energy consumption is low, the rate of finished products is high, and the production cost is reduced; and meanwhile, the glaze surface is very special in cracking, uniform and clear in lines, and full of the glaze surface, thereby giving a special aesthetic feeling to people.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a high-strength medium-temperature cracked glaze ceramic product and a manufacturing method thereof. Background technique [0002] The generation of crack glaze, like kiln glaze, was accidental at first. Moreover, glaze cracks are originally a defect in firing, but when the glaze cracks of some products are very special, the lines are uniform and clear, and they are all over the surface of the vessel, giving people a special sense of beauty. After being inspired, I summed up my experience and consciously created the cracks on the sleeve surface, thus gradually creating the crack glaze. Its glaze surface is covered with many small cracks, the lines are sparse or dense, thick or thin, long or short, curved or straight, like cracks, crab claws, brocade, and water patterns. The surface of the porcelain forms a distinctive decoration. [0003] The reason for the cracke...

[0004] Generally, when firing glaze, about 1100°C belongs to low-temperature firing, about 1200°C belongs to medium-temperature firing, and 1300°C belongs to high-temperature firing. The crackle glaze has made the corresponding products popular with many consumers because of its unique crackle effect, but the existing crackle glaze On the one hand, the glaze effect of ceramic products is unstable, and the glaz
