Method for high-temperature firing of underglaze color crackle ceramic
The invention discloses a method for high-temperature firing of underglaze color crackle ceramic. The method comprises steps as follows: 92-95 parts of zirconia, 1-3 parts of silicon oxide, 1-2 parts of feldspar, 0.5-1.5 parts of kaolin, 1.5-2.5 parts of zirconium silicate and 0.5-5 parts of a fluorine-containing additive are weighed out for ball milling and then mixed with an inorganic nano-particle dispersion liquid, and a ceramic clay body is prepared; 30-35 parts of feldspar powder, 5-10 parts of calcium magnesium powder, 3-8 parts of melilite, 5-10 parts of calcite, 3-8 parts of dolomite, 5-10 parts of kaolin, 20-25 parts of silicon oxide, 5-10 parts of zinc oxide, 3-6 parts of calcium carbonate, 3-6 parts of a heat-resistant agent and 5-15 parts of water are weighed out for ball milling, and then transparent feldspar glaze slurry is prepared; the obtained ceramic clay body is placed in the slurry for soaking and placed in a kiln for firing after being dried. The prepared finished product has the concave-and-convex stereoscopic crackle effect and the good shock resistance and heat stability.
