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.
