Problems solved by technology

However, with the extensive use of zircon sand, domestic reserves of high-grade zircon sand are insufficient, and a large number of imports have led to a rise in the price of high-grade zircon sand. Moreover, zircon sand is associated with radioactive elements, and its radioactive elements are processed in the later stage. Difficult to remove, harmful to human health

Abstract

The invention discloses opacified glaze with no zircon sand, which comprises the following components in parts by weight: 5-10 parts of zirconium silicate, 5-15 parts of zinc oxide, 5-10 parts of boric acid, 10-20 parts of potash feldspar, 2-5 parts of potassium nitrate, 4-10 parts of dolomite, 8-15 parts of calcite, 6-15 parts of kaolin, and 30-40 parts of quartz. The opacified glaze with no zircon sand replaces zircon sand with zirconium silicate, therefore, the harm to the health of human body is reduced, and the production cost is reduced at the same time.

Description

technical field [0001] The invention relates to an opacified glaze, in particular to an opacified glaze without zircon sand. Background technique [0002] Opaque glaze is a method of common ceramic decoration and is widely used. Opaque glaze is a white opaque glossy glaze, which is due to the presence of a second or third phase substance in the glaze glass that has a different refractive index from the matrix glass and has a small volume. When the light passes through the glaze layer, the opacity particles cause light to scatter The effect thus causes the glaze layer to be opaque. [0003] According to the aggregation state of opacified particles, opacified glazes can be divided into three categories: one is that there are a certain number of tiny crystals in the matrix glass, which is called crystal phase opacified glazes; the other is that liquid-liquid separation occurs during the cooling process of the glaze melt. phase, the second phase glass with a high degree of mic...
