The invention discloses a light-weight ceramic brick, which is a light-weight ceramic brick fired at high temperature and has a honeycomb-like internal structure of closed pores. The invention also discloses a preparation method of the above-mentioned lightweight ceramic tiles, which is formed by dry pressing after wet ball milling, sieving, iron removal, spraying drying tower and powder spraying on the vitrified brick polishing waste produced in large quantities in the ceramic industry at present. Method forming, or kneading using wet extrusion molding, and then firing products in continuous or batch kilns. Manufacture a kind of lighter quality ceramic tiles, aiming at the insufficient use of waste materials in the past, more effectively utilize industrial waste residues in large quantities, and because of its light structure, it can be used in the decoration of high-rise building walls, It has good properties such as light weight, high strength, heat preservation, and sound absorption, and it can significantly reduce the weight of the wall structure. At the same time, it also has the characteristics of easy transportation, easy construction, and fast speed. It has great advantages in saving energy and reducing the weight of buildings. The outstanding advantage is that it is an environment-friendly building ceramic decoration material.
