Abstract

The invention discloses a metallic glaze. The metallic glaze comprises the following components: 5-25 parts by weight of feldspar, 10-30 parts by weight of albite, 25-40 parts by weight of quartz, 1-15 parts by weight of calcite, 5-20 parts by weight of kaolin, 15-40 parts by weight of frit powder, 0.1-5 parts by weight of titanium oxide, 0.5-5 parts by weight of vanadium pentoxide, 5-20 parts by weight of manganese dioxide, 0.1-5 parts by weight of copper oxide, 0.1-3 parts by weight of cobalt oxide and 0.1-5 parts by weight of nickel oxide, wherein the frit powder comprises potassium chloride, sodium chloride, silica, alumina, magnesia, boric acid and spodumene. The invention also discloses a preparation method for the metallic glaze. With the formula and preparation method for the metallic glaze, the prepared metallic glaze has excellent metallic luster and high glaze hardness and totally appears to be golden yellow.

Description

technical field [0001] The application relates to the technical field of ceramic production, in particular to metallic glaze and its preparation method. Background technique [0002] Metallic glaze is a special art glaze in the ceramic industry glaze. It is a special glaze that makes the glaze reflect metallic luster and has a strong glass phase. The surface of the ceramic tile with metallic glaze presents a metallic luster and can present a variety of colors. The glazed surface with metallic luster has an elegant and luxurious artistic effect, and is favored by the market and consumers. [0003] Metallic glazes are made by adding transition metal oxides to the basic glaze and firing at a high temperature to achieve saturation and precipitate crystals to make the glaze surface produce metallic luster. However, the existing metallic glazes are not resistant to high temperatures when fired, and need to be repeatedly fired, and the glazed surface of the finished product is no...
