Alumina-silicon carbide ceramic serving as lining of dense medium cyclone and preparation method of alumina-silicon carbide ceramic
The invention relates to an alumina-silicon carbide ceramic serving as a lining of a dense medium cyclone and a preparation method of the alumina-silicon carbide ceramic and belongs to the field of ceramic materials. The alumina ceramic lining is prepared from the following main raw materials including A, alpha-Al2O3 powder with purity of 95 percent and B, SiC powder. The preparation method comprises the following steps: burdening the A and the B according to the formulated proportion, and putting the formulated materials into a ball mill to carry out ball milling; then carrying out spray drying granulation on uniformly mixed slurry, and then sieving; and adopting a dry pressing method, wherein the sintering process is carried out in a high-temperature atmosphere oven with protection of N2, and the sintering temperature is 1450 DEG C. According to the alumina-silicon carbide ceramic and the preparation method disclosed by the invention, the wear resistance of the alumina ceramic lining with low cost is improved.
