Low-temperature cracked glaze, ceramic product prepared from same and preparation method of ceramic product

Abstract

The invention relates to a low-temperature cracked glaze, a ceramic product prepared from the same and a preparation method of the ceramic product, belonging to the technical field of ceramics. The low-temperature cracked glaze comprises the following components in parts by mass: 390-410 parts of nepheline syenite, 48-52 parts of quartz, 48-52 parts of heavy calcium carbonate, 780-820 parts of first glaze frits, 19-21 parts of light calcium carbonate, 19-21 parts of second glaze frits and 76-84 parts of copper carbonate. The cracked glaze can be sintered at relatively low temperature through meticulously blending a glaze material of the low-temperature cracked glaze, so that energy sources are effectively saved; the ceramic product prepared from the low-temperature cracked glaze by using the method disclosed by the invention is not only high in finished product rate up to higher than 95, but also integrated and attractive in glaze surface and remarkable in crack effect; the ceramic product sintered by using the glaze material disclosed by the invention is deep green in glaze surface and uniform and meticulous in crack so as to have favorable application and market prospects.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a low-temperature cracked glaze, a low-temperature cracked glaze ceramic product prepared by using the same, and a preparation method. Background technique [0002] Crackle glaze refers to the fine cracks on the glaze layer of ceramic products, which makes ceramic products have specific artistic effects and is favored by people. The formation mechanism of the cracked glaze is that the expansion coefficient of the glaze is greater than that of the billet. When the product is cooled, the shrinkage of the glaze is greater than that of the billet, which causes cracks in the glaze layer; the greater the difference in shrinkage, the greater the degree of cracking ; The smaller the elasticity of the glaze, the larger the crack will be.

Problems solved by technology

[0003] Although there are many cracked glazes at present, the raw material ratio and firing process of cracked glazes are still worthy of people's exploration. Generally, when firing glazes, about 1100°C belongs to low-temperature firing, about 1200°C belongs to medium-temperature firing, and about 1300°C belongs to high-temperature firing. High-temperature firing. At present, most of the cracked glazes are fired at medium and high temperatures. Although high-temperature firing can ensure a good cracking effect, most cracked glazes are poor in adapting to rapid high-temperature firing, and defective products are relatively high. More energy and time are consumed, the production efficiency is lower, and the cost is higher
