Embodiment 1

[0014] A kind of black glaze material for ceramics, according to the composition by weight: 18 parts of albite feldspar, 20 parts of goat rock, 15 parts of calcite, 8 parts of calcined ferric oxide, 15 parts of fluvo-aquic soil, 12 parts of grass ash, 6 parts of manganese powder Parts, 6 parts of barium carbonate.

[0015] According to the composition ratio of the ceramic black glaze of the present embodiment, the preparation method of the black glaze is that the black glaze is ball milled for 14 hours according to the mass ratio of raw material: ball stone: water=1.1: 1.5: 0.9, and the fineness is The 260 mesh sieve residue is less than 0.5%, and then the product is obtained.

[0016] Before ball milling, ferric oxide is calcined at high temperature.

[0017] Before ball milling, the goose and sheep mountain stone is roughly machined to 40-60 mesh.

[0018] The prepared black glaze is glazed on the body, and the temperature is gradually raised to 1230°C for high temperature...

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...
