Red mud is a by-product in the production of alumina, and is the most large number of solid waste in Non-ferrous metallurgical industry. China is the world's second largest producer of alumina, the annual emissions of red mud reach to millions of tons. The low efficiency of utilization of red mud has brought enormous environmental pressure to China。Therefore, how to use of red mud has received extensive attention. The feasibility of preparing ceramic using red mud and flying ash as main raw materials was investigated. The influences of roasting temperature, roasting time, material composition, forming pressure and other factors on the compressive strength and bending strength of sintered product were discussed. The research results indicates that it is feasible to prepare ceramic materials with red mud and fly ash as the main raw materials, and the product completely meets the requirements of Chinese national standard (GB/T4100-2006).
