Blue black metallic luster glaze and preparation method thereof

Abstract

The invention relates to blue black metallic luster glaze which is prepared from the following components in parts by weight: 35-45 parts of an intermediate temperature lead-free high sodium and calcium frit, 15-20 parts of quartz, 5 parts of calcium carbonate, 3 parts of barium carbonate, 10 parts of calcined zinc oxide, 7 parts of kaolin, 4 parts of titanium dioxide, 3 parts of iron sesquioxide,8-10 parts of manganese dioxide, 3 parts of copper oxide, 2-4 parts of cobalt oxide, 1-2 parts of nickel oxide and 1-2 parts of vanadium pentoxide. The invention also provides a preparation method ofthe surface glaze. The preparation method comprises the following steps: mixing and ball-milling the glaze; applying the glaze; and carrying out primary firing. According to the blue black metallic luster glaze prepared by the invention, as enough metallic oxides such as iron sesquioxide, manganese dioxide, copper oxide, cobalt oxide, nickel oxide and vanadium pentoxide are introduced into the glaze, when the oxide of manganese reaches a saturated state, metals are separated out from the glaze surface; by adding copper oxide, a metal film is formed on the glaze surface; and by adding a certain amount of cobalt oxide, the glaze surface finally shows blue black metallic luster.

Description

technical field [0001] The invention belongs to the technical field of ceramics, in particular to a blue-black metallic luster glaze and a preparation method thereof. Background technique [0002] In recent years, due to the influence of the external economic and social environment, the competition in the porcelain products market has become increasingly fierce. In the research and development and production of ceramic handicrafts, more and more emphasis is placed on individuality and uniqueness. From the history of glaze decoration of ceramic handicrafts, abstract and unique glaze color and figurative decoration have always been two important contents of ceramic handicraft decoration. [0003] To form a metallic luster effect on the ceramic surface, the following three methods are generally used, (1) thermal spraying process, directly spraying organic or inorganic metal salt solution on the hot ceramic glaze; (2) low-temperature double firing process, in The sintered cera...
