Preparation of double-layer glass-ceramic/ceramic tile from bauxite tailings and red mud

Double-layer glass-ceramic/ceramic tiles made from bauxite tailings and red mud were prepared using a single firing powder processing route. The influence of the preparation method used for the green bodies on the microstructure and mechanical properties of the final products was investigated. The macroscopic appearance, microstructure, and mechanical properties indicated that the production of double-layer glass-ceramic/ceramic tiles may be an attractive method for recycling industrial waste into building materials.
