Embodiment 1
[0039] A method for preparing architectural decorative kiln art ceramics, comprising the following steps:
[0040] A. Ingredients: Weigh the green body raw materials according to weight percentage, and the green body raw materials are composed of the following weight percentage components:
[0041]
[0042]
[0043] B. Pulping: Weigh the raw materials according to the ratio in A, and put the mixed raw materials into the ball mill according to the ratio of material: ball: water = 1: 2: 0.35; the ball mill will form a 250-mesh sieve residue of 1.2 ~ 1.7% slurry.
[0044] C. Powder making: the slurry obtained in step B is made into powder through a spray dryer, and then aged for 2 to 3 days.
[0045] D. Press molding: press the aged powder obtained in step C into brick adobe.
[0046] E. Drying: Press the powder obtained in step C into adobe, and then gradually increase the temperature to 200°C. After drying, the moisture content of the adobe is 0.5-1%, and the temperatur...

[0057] The billet is composed of the following components by weight percentage: 15% of kaolin, 12% of weathered sand, 35% of potassium feldspar, 22% of low-fired clay, and 7% of refined white sand. Waste base powder 7%, black talc 2%;
[0058] The bottom glaze is composed of the following components by weight percentage: potassium feldspar 19%, porcelain sand 10%, kaolin 10%, zinc oxide 5%, calcined talc 10%, barium carbonate 15%, dolomite 8%, calcium carbonate 11% , Calcium Phosphate 10%, Aluminum Oxide 2%
[0059] The surface glaze is composed of the following components by weight percentage: potassium feldspar 23%, porcelain sand 5%, kaolin 10%, zinc oxide 17%, calcined talc 10%, zirconium silicate 10%, titanium oxide 18%, glass powder 5% %, cobalt oxide 2%.
[0060] Other steps are the same as in Embodiment 1.
Embodiment 3
[0062] The billet is composed of the following components by weight percentage: 12% of kaolin, 10% of weathered sand, 30% of potassium feldspar, 28% of low-fired clay, and 9% of refined white sand. Waste base powder 6%, black talc 5%;
[0063] The bottom glaze is composed of the following raw materials in weight percentage: 16% albite feldspar, 15% porcelain sand, 7.5% kaolin, 6.5% zinc oxide, 7.5% calcined talc, 16% barium carbonate, 7% dolomite, 16% calcium carbonate, Calcium phosphate 5%, aluminum oxide 3.5%;
[0064] The surface glaze is composed of the following raw materials in weight percentage: 22% albite, 8% porcelain sand, 8% kaolin; 22% zinc oxide; 5% calcined talc; 15% titanium oxide, 12% zirconium silicate, and 8% glass powder , colorant 1.2%.
[0065] Other steps are the same as in Embodiment 1.
[0066] The crystal flower test results of kiln-changing artistic ceramic tiles are shown in the attached figure.
