The invention discloses an acid-resistant ceramic tile, relating to the technical field of building materials. The acid-resistant ceramic tile is composed of the following raw materials in percentage by weight: 60-70% of SiO2, 15-25% of Al2O3, 3-5% of K2O, 1.5-2% of Na2O, 2-2.5% of CaO, 0.8-1.2% of MgO, 0.5-0.8% of Fe2O3 and 5-8% of TiO2. Compared with the prior art, the acid-resistant ceramic tile has the advantages of high acid resistance and low water absorptivity, and has excellent corrosion-resistant actions on wet chlorine, brine, hydrochloric acid, sulfuric acid, nitric acid and other acids except for hydrofluoric acid and hot concentrated phosphoric acid as well as alkalis with any concentration. The acid-resistant ceramic tile is suitable to be attached to the inside of reaction tanks and oxidation tanks in chemical industry, metallurgy, coking, thermal power, petrochemistry and other industries, and is capable of preventing the tank body from being damaged due to acid and alkali corrosion, avoiding the accidents and ensuring the normal production.
