Abstract

The invention belongs to the technical field of ceramic glazes and discloses a special ceramic metal glaze for ceramics. The special ceramic metal glaze is prepared from, by weight, 20-36 parts of potassium feldspar, 18-24 parts of china clay, 10-21 parts of copper oxide, 7-12 parts of silicon carbide, 5-9 parts of boracic acid and 3-8 parts of titanium dioxide. The invention further discloses a preparation method of the special ceramic metal glaze. Raw material components in a glaze formula of the ceramic metal glaze are extensive in source and low in cost. By synergistic effects of copper oxide, silicon carbide and boracic acid in the formula of the ceramic metal glaze, the firing temperature is lowered while chemical stability and hardness of the ceramic metal glaze are evidently improved, and energy consumption reduction and production cost reduction are realized.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a special ceramic metal glaze for ceramics. Background technique [0002] Metallic glaze is a special artistic glaze in the ceramic industry glaze. It is mainly applied on antique bricks and tiles, and also on bottles, vases or art porcelain for daily use. The surface of ceramic products with metal glaze presents a metallic luster and can present various colors, such as red, yellow, silver, blue, black, etc. Glazed tiles with metallic luster are favored by the architectural ceramics industry and consumers because of their elegance and heavy temperament, but they are expensive, and the metal glazes in the prior art have limited application range due to poor chemical stability and hardness. to a larger limit. Contents of the invention [0003] The object of the present invention is to provide a special ceramic metal glaze for ceramics in order to overcome the problems in...
