High-brightness ceramic tile and production process thereof

The invention relates to the technical field of ceramic tile production, and particularly discloses a high-brightness ceramic tile and a production process thereof. The ceramic tile comprises a green body and glaze coated on the green body, wherein the glaze is prepared from the following raw materials in parts by weight: 20 to 45 parts of potassium granite, 15 to 30 parts of wollastonite, 10 to 20 parts of golden sand, 8 to 15 parts of zircon sand, 8 to 20 parts of modified nano aluminum oxide, 2 to 8 parts of sodium carboxymethyl cellulose and 45 to 60 parts of water; the preparation method comprises the following steps: uniformly mixing green body raw materials, and grinding to obtain a blank; uniformly mixing the raw materials of the glaze except water, grinding, adding water, and uniformly mixing to obtain the glaze; pressing the blank into a green body, and drying to obtain a green body; uniformly coating the glaze on the green body, drying to obtain a pre-formed ceramic tile, firing the pre-formed cera
