The invention relates to a ceramic material prepared from red mud, and a preparation method of the ceramic material, belonging to the field of comprehensive utilization of resources of solid wastes. The ceramic material is prepared by mixing the following raw materials by mass percent: 10-70% of red mud, 0-60% of clay, 5-35% of silicon-rich aluminum raw material, 5-40% of quartz raw material and 0-30% of magnesium-rich raw material; the preparation method adopts the traditional ceramics preparation technology, and comprises the steps of crushing the raw materials, blending, grinding, granulating, molding and carrying out other technologies to form a ceramic green body, drying the ceramic green body, enabling the dried ceramic green body to enter a ceramic kiln, and firing to obtain the ceramic material product, wherein the sintering temperature is 1060-1180 DEG C, the sintering time is 35-70 minutes, the breaking strength value of the prepared ceramic material exceeds 35MPa, the water absorption value of the prepared ceramic material is less than 1%, and if a optimal ratio is adopted, the breaking strength value of the ceramic material exceeds 100MPa, and the water absorption value of the ceramic material is less than 0.5%. After the preparation method is adopted, the red mud can be used for producing general construction ceramics/ceramic sintered bricks and high-strength industrial ceramic materials; the preparation method is easy and feasible, and is beneficial to industrial production.
