Ceramic glaze and preparation method thereof

[0031] Embodiment 1: A kind of high-performance matte glaze and preparation method thereof

[0032] The mineral material of the ceramic glaze of the present embodiment consists of (weight content): zinc oxide 4%, barium carbonate 10%, feldspar 40%, aluminum oxide 10%, talc 5%, calcite 8%, kaolin 8%, silicon Zirconium acid 15%.

[0033] The corresponding chemical composition of the glaze is: SiO 2 49.4%, Al 2 o 314.6%, CaO 5.4%, MgO 1.8%, BaO 8.3%, ZnO 4.3%, K 2 O 4%, Na 2 O 1.7%, ZrO 2 10.3%, Fe 2 o 3 0.1%, TiO 2 0.1%.

[0034] Concrete preparation steps are:

[0035] (1) Weigh mineral raw materials according to the above formula, add water ball mill (material: water weight ratio is 100:45) for 8 hours to obtain 0.3% glaze slurry with 325 mesh sieve. After the glaze slurry is iron-removed and sieved, the powder with a moisture content of about 7% is obtained by spray drying, and the powder is transported to a press and pressed into shape;

[0036] (2) Fire the pre
