Abstract

The invention relates to a mixture ratio of raw materials of a grey blue glaze. The grey blue glaze comprises the following compositions by weight percentage: 30 to 35 percent of quartz, 32 to 38 percent of feldspar, 8 to 11 percent of talcum, 2 to 5 percent of clay, 6 to 9 percent of limestone, 3 to 5 percent of aluminum oxide, 7 to 9 percent of zirconium silicate, 0.01 to 0.05 percent of manganese oxide, 0.1 to 0.4 percent of ferric oxide, 0.01 to 0.05 percent of chromic oxide, 0 to 0.3 percent of cobalt oxide, 0 to 1 percent of dispersant and 0 to 1 percent of carboxymethyl cellulose sodium. The grey blue glaze is prepared by steps of drying, grinding, screening, iron removal, aging, glaze spraying and firing according to the mixture ratio of the grey blue glaze. The mixture ratio of raw materials of the grey blue glaze and the method for firing the grey blue glaze can improve the appearance quality of ceramic pieces and the performance of glaze layers and can meet requirements for batch production and ensure high qualification rate of products and good economic benefits due to the adoption of the prior equipment in the firing process.

Description

technical field [0001] The invention belongs to the field of ceramic manufacturing, and relates to a gray-blue glaze, in particular to a raw material ratio of the gray-blue glaze and a firing method thereof. Background technique [0002] Since entering the 21st century, the rapid development of China's economy has made users have higher and higher quality requirements and expectations for products, resulting in the appearance quality of products produced by electric porcelain manufacturers cannot meet the requirements of users, especially for the production quality of gray blue glaze. However, due to the aging of the raw material formula and the firing process, the surface of the fired gray-blue glaze is not smooth enough, and the color is not bright enough. [0003] The firing process of electric porcelain, that is, the firing system of electric porcelain, is the requirement for the flame properties of different temperature sections in the firing curve when the temperature ...
