Abstract

The invention discloses an anorthite micro-crystal transparent glaze and a preparation method thereof, and relates to a ceramic-used glaze material. The anorthite micro-crystal transparent glaze comprises the following ingredients by mass percentage: 1%-5% of Na2O, 1%-5% of K2O, 12%-18% of Al2O3, 15%-20% of CaO, 2%-5% of MgO, 2%-7% of ZnO, 2%-7% of high-boron frit and the balance of SiO2. The fineness of the glaze material is less than 0.15% as the residue of a 250-mesh sieve; the preparation method comprises the following technological processes: testing raw materials, matching the raw materials, ball-milling, detection, milling out, sieving, adjusting the density of glaze slip to 1.35-1.4g / cm<3>, glazing, sintering and obtaining a finished product. A sintering system is described as follows: preserving heat at the temperature of 1,200-1,210 DEG C for 30-40min, cooling to the temperature of 860-880 DEG C and preserving heat for 30-40 min. Anorthite crystals grow on a glaze surface of the anorthite micro-crystal transparent glaze prepared by the invention, so that the hardness, wear resistance, mar-resistance and corrosion resistance of the glaze surface are improved, and the defect that scratches are easily caused on the glaze surface of the transparent glaze is overcome.

Description

technical field [0001] The invention relates to the field of ceramic glazes, in particular to an anorthite microcrystalline transparent glaze and a manufacturing method thereof. Background technique [0002] Ceramic glazed floor tiles are flat, bright and clean, and have a variety of designs and colors. With its gorgeous decorative effect without polluting the environment, it has become a widely used decorative material. However, its glaze is a layer of glass transparent glaze after all. Sand introduced by hard-soled shoes can scratch the glaze. If it is worn for a long time, it may even reveal mottled tire background color. Naturally influenced durable decorative effect. Glass-ceramics has the advantages of high mechanical strength, high wear resistance, and high hardness. For many years, people have tried to use glass-ceramics in ceramic glazes, but the precipitation of crystals in the glaze layer will affect the light transmittance of the glaze layer. Therefore, it h...
