Black glaze for ceramics and preparation method thereof

Abstract

The invention discloses a black glaze for ceramics and a preparation method thereof. According to parts by weight, the composition comprises: 14-19 parts of albite, 20-23 parts of goat rock, 13-15 parts of calcite, and 6-8 parts of ferric oxide Parts, 15-18 parts of fluvo-aquic soil, 12-16 parts of grass ash, 4-6 parts of manganese powder, 4-6 parts of barium carbonate, black glaze according to raw materials: ball stone: water = 1-1.1: 1.5: 0.7-0.9 The mass ratio ball milling is 12-14 hours, and the fineness is less than 0.5% after sieving with 260 meshes, and then the product is obtained. The optimal composition and proportion of the black glaze for ceramics provided by the present invention is optimized according to a large number of experiments, so that the glaze and the green body can be well combined, the reaction can be completed quickly, and the color of the glaze is stable, bright and glossy Good degree of black and rosy, which improves the yield of finished products.

Description

technical field [0001] The invention belongs to the technical field of ceramic glaze production, and in particular relates to a black glaze for ceramics and a preparation method thereof. Background technique [0002] Ceramics are widely used in various fields because of their smoothness, compactness and many other advantages. During the preparation of ceramics, various low-temperature colors are often applied to pure black glazes, and black glazes become various beautiful colors. High-profile and elegant ceramic glaze can be obtained, but its glaze surface of the black glaze of the prior art is not bright enough. The color is not uniform enough, so it is necessary to design a ceramic black glaze with moist, bright glaze and black as lacquer on the basis of reproduction technology. Contents of the invention [0003] The object of the present invention is to provide a kind of scarlet glaze for ceramics and a preparation method thereof in order to solve the problems mentione...

[0002] Ceramics are widely used in various fields because of their smoothness, compactness and many other advantages. During the preparation of ceramics, various low-temperature colors are often applied to pure black glazes, and black glazes become various beautiful colors. High-profile and elegant ceramic glaze can be obtained, but the glaze surface of the black glaze in the prior art is not bright enough

The color is not uniform enough, so it is necessary to design a ceramic black glaze with moist, bright glaze and black as lacquer on the basis of reproduction technology.
