Example Embodiment

[0027] Example 1

[0028] This embodiment is performed according to the following steps:

[0029] 1) First, prepare the following components according to the total weight percentage: quartz: 32.88%; feldspar: 38%; talc: 11%; clay: 2%; limestone: 6%; alumina: 3%; zirconium silicate: 7% ; Manganese oxide: 0.01%; iron oxide: 0.1%; chromium oxide: 0.01%, of which zirconium silicate is 3 micron grade;

[0030] 2) Then put the above solid raw material components into a drying room respectively for baking, in which the moisture mass percentage content of quartz, clay and feldspar is controlled within 5%; the moisture mass percentage content of other solid raw material components is controlled within Within 1%;

[0031] 3) According to the raw material ratio, add all the raw material components to the ball mill one by one, and add water, and the mass percentage content of the water is required to be controlled at 32%. Ball mill for 12 hours to form a glaze slurry;

[0032] 4) Pass the...

Abstract

The invention relates to a grayish blue glaze. The grayish blue glaze comprises the following components by percent of total weight: 30%-35% of quartz, 32%-38% of feldspar, 8%-11% of talc, 2%-5% of clay, 6%-9% of limestone, 3%-5% of aluminum oxide, 7%-9% of zirconium silicate, 0.01%-0.05% of manganese oxide, 0.1%-0.4% of ferric oxide, 0.01%-0.05% of chromic oxide, 0%-0.3% of cobaltous oxide, 0%-1% of dispersing agent, and 0%-1% of sodium carboxymethyl cellulose, wherein the dispersing agent is ceramic dispersing agent A15, and zirconium silicate is 3 micron grade. A firing method for the grayish blue glaze comprises following specific steps of stoving, grinding, sieving, removing iron, ageing, spraying glaze and firing. The firing method not only can greatly improve the appearance quality and glaze performance of the ceramic, but also can guarantee high percent of pass of the product, and has good economical benefits.

Description

technical field [0001] The invention belongs to the field of ceramic manufacture, and relates to a gray-blue glaze, in particular to a 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 rises, so as to succ...
