Abstract
The invention discloses metallic luster glaze and a preparation method thereof. The metallic luster glaze consists of the following components in parts by mass: 10 to 20 parts of albite, 8 to 10 parts of boron frit, 10 to 12 parts of perlite, 15 to 17 parts of calcined kaolin, 40 to 50 parts of argil, 16 to 18 parts of vermiculite, 15 to 25 parts of sandy loam soil, 5 to 7 parts of zinc oxide, 6 to 8 parts of cristobalite, 10 to 20 parts of calcined talc, 6 to 7 parts of aluminium oxide, 14 to 18 parts of gypsum powder and 1 to 2 parts of a catalyst. According to the metallic luster glaze and the preparation method thereof, the chemical composition of the formula is optimized, a plurality of superfine ferric oxide crystallization grains are separated out of the glaze when the glaze is condensed at the high-temperature sintering later period, and a plurality of isolated single lamelliform crystal flowers which glitter like small gold foils are formed, so that the Venus-like metallic glaze effect is played.
Description
technical field [0001] The invention relates to the technical field of ceramic production, in particular to a metallic luster glaze and a preparation method thereof. Background technique [0002] At present, with the improvement of people's living taste, higher decorative requirements have been placed on the glazed surface of sanitary ceramics, which not only have use value but also have ornamental value. Due to the elegant and resplendent artistic effect of metal decorative materials, glazed surfaces with metallic luster are becoming more and more popular. Venus glaze is a special type of microcrystalline glaze. Its mechanism is that when the crystallization agent condenses in the late stage of high-temperature firing, many fine iron oxide crystal grains are precipitated to form gold sand. These extremely fine gold grain crystals are not floating on the glaze. above the surface, but buried beneath the surface of the glaze, suspended in a transparent glass matrix. Through ...
