Art glaze with high glaze surface hardness and preparation method thereof

Abstract

The invention provides art glaze with high glaze surface hardness and a preparation method thereof. The art glaze with high glaze surface hardness is prepared from the following raw materials in percentage by mass: 60 to 63 percent of SiO2, 4 to 6 percent of Al2O3, 0.1 to 0.3 percent of Fe2O3, 1 to 3 percent of B2O3, 3 to 5 percent of MgO, 1 to 3 percent of BaO, 5 to 7 percent of Cao, 4 to 6 percent of TiO2, 1 to 3 percent of K2O, 1 to 3 percent of Na2O and 0.3 to 0.5 percent of Li2O wherein ignition loss is 6 to 8 percent. The art glaze specifically comprises the following raw materials: 22.04% of SiO2, 4.66% of AL2O3, 0.28% of Fe2O3, 2.64% of B2O3, 3.72% of MgO, 2.24% of BaO, 6.02% of CaO, 25.20% of TiO, 2.86% of K2O, 1.32% of Na2O and 0.44% of Li2O, wherein the ignition loss is 7.46%. According to the art glaze with high glaze hardness and the preparation method thereof provided by the invention, the art glaze is reasonable in material selection, clear in glaze surface and controllable in firing temperature, the wear resistance of the finished glaze is improved by optimizing the raw materials and the sizes of the raw materials, and the surface of the art glaze presents good glossiness and is not easy to wear, and the art glaze has extremely high art and market values and facilitates the improvement of an industrial generic technology of Jun ware.

Description

technical field [0001] The invention relates to the technical field of art glazes, in particular to an art glaze with high glaze surface hardness and a preparation method thereof. Background technique [0002] Ceramic glaze is a kind of artistic glaze. It is a colorless or colored glassy thin layer covering the surface of ceramic products. Glaze is a kind of silicate. The glaze applied on ceramics is generally made of quartz, feldspar, clay As a raw material, after grinding and adding water, it is coated on the surface of the green body and melted by roasting at a certain temperature. When the temperature drops, a glassy thin layer on the ceramic surface is formed. [0003] It makes ceramics increase mechanical strength, thermal stability, dielectric strength and prevent liquid and gas erosion. [0004] In related technologies, there are certain defects in the use of art glazes, such as the hardness and wear resistance of art glazes are reduced under long-term use, and are ...
