Abstract

The invention belongs to the technical field of ceramic glazes and particularly relates to a granular double-layer reaction glaze and a preparation method. The granular double-layer reaction glaze comprises the following ingredients in parts by weight: a ground glaze: 30-40 parts of soda feldspar, 5-15 parts of quartz, 5-15 parts of wollastonite, 2-6 parts of calcined alumina, 25-35 parts of kaolin and 15-25 parts of toner; and an overglaze: 35-45 parts of high-boron clinker, 15-25 parts of quartz, 5-10 parts of wollastonite, 5-15 parts of spodumene, 10-20 parts of calcined zinc oxide, 5-15 parts of kaolin, 5-10 parts of calcined talcum, 5-10 parts of titanium dioxide powder and 5-15 parts of zirconium silicate. The granular double-layer reaction glaze is short in firing time and has relatively high thermal shock resistance and glazed surface hardness.

Description

technical field [0001] The invention belongs to the technical field of ceramic glazes, and in particular relates to a granular double-layer reactive glaze and a preparation method. Background technique [0002] At present, the domestically produced 1200-1250°C medium-temperature kiln color-changing glaze products are mainly ordinary reaction glazes, the reaction effect is rough and unstable, and the aesthetic feeling of the glaze is not good enough to meet the increasing aesthetic and material needs of consumers. Young consumers yearn for a better life in the future and pursue higher-grade living ceramics, so granular double-layer reactive glazes appear. Granular double-layer reactive glaze refers to the glaze with Duca reaction effect and granular crystallization effect on the surface. Its thermal shock resistance and glaze hardness are better than ordinary reactive glaze, and it is very stable. Ordinary reactive glazes are mainly ordinary kiln-changing colored glazes, and...
