Method for preparing mullite multiphase ceramic by low-temperature sintering of bauxite tailings
The invention discloses a method for preparing mullite multiphase ceramic by low-temperature sintering of bauxite tailings, and belongs to the technical field of high-value utilization of the bauxite tailings and ceramic preparation. According to the invention, bauxite tailings, bauxite clinker and lithium chinastone are adopted as main raw materials, and the mullite multiphase ceramic is prepared through the processes of batching, ball milling, molding and low-temperature sintering. The mullite multiphase ceramic material prepared by low-temperature sintering of the bauxite tailings has the characteristics of high compressive strength, small linear shrinkage rate, high volume density and simple preparation process, and can be used in industries such as high-value utilization of the bauxite tailings and ceramics. The required raw materials are easy to obtain, the preparation process is simple, the utilization amount of the bauxite tailings is high, the problems of massive accumulation of the bauxite tailings and pollution and damage to the environment can be solved, and waste is turned into wealth; and by adding the bauxite tailings, the sintering temperature of the mullite multiphase ceramic can be reduced, the cost and the energy consumption are low, and high-value utilization of the bauxite tailings is realized.
