[0029] A method for preparing a fibrous nano-alumina modified ceramic glazed tile. The ceramic body can be prepared from known ceramic raw materials according to a conventional method, or can be made from the powder of the ceramic body defined in the application. For ceramic raw materials or The powder made into the ceramic green body is subjected to steps such as ball milling, powder spraying and granulation, and compaction drying to prepare the ceramic green body; specifically, the ceramic raw materials used in the ceramic green body in the following examples are calculated by weight percentage, including the following: Chemical composition: SiO 2 : 67%, A1 2 o 3 : 21.5%, K 2 O: 3.5%, Na 2 O: 2%, MgO: 0.5%, CaO: 0.3%, Fe 2 o 3 IL: 0.5%, IL: 4.7%; the remaining 0.6% to 0.8% of the powder made of full-throwing brick body is passed through a 250-mesh sieve.
