Abstract

The invention discloses a white milky glaze, white milky glaze ceramic products and a preparation method thereof. The white milky glaze comprises the following raw materials in parts by weight: 20-25 parts of potassium feldspar, 22-27 parts of albite , 8-12 parts of calcite, 16-20 parts of quartz, 10-14 parts of talc, 4.5-5.5 parts of bentonite, 6-8 parts of strontium oxide, 5-7 parts of barium oxide, 6-9 parts of magnesium oxide, and 5 parts of titanium oxide ~6 parts, barium zirconate titanate 2.5~3.5 parts, zirconium silicate 15~20 parts, yttrium oxide 4~6 parts. The white opacity glaze ceramic product prepared by the present invention has the advantages of good opacification effect on the glaze surface (opacity glaze), smooth and smooth glaze surface, good gloss, exquisite appearance, etc., and has high whiteness and wear resistance of the glaze surface. Good and firm.

Description

technical field [0001] The invention relates to the field of ceramic products, in particular to a white opaque glaze, a white opaque glaze ceramic product and a preparation method thereof. Background technique [0002] Opaque glaze is a method of common ceramic decoration and is widely used. Opaque glaze is white opaque glossy glaze. It is due to the fact that there is a second or third phase material in the glaze glass that has a different refractive index from the matrix glass phase and has a small volume. When the light passes through the glaze layer, the opacity particles cause the light to scatter and make the glaze layer opaque. The phenomenon. [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 crystals occur in the glaze melt during cooling....
