The invention relates to the technical field of preparation of refractory ceramics, in particular to a preparation method of refractory ceramics based on alumina and alumina aggregate, which comprises the following steps: S1, mixing alumina powder, alumina aggregate, clay and an additive according to a certain proportion to prepare uniform slurry; s2, injecting the slurry into a plaster mold, and performing slip casting to obtain a green body; s3, after the green body is demolded, drying treatment is carried out, and moisture is removed; and S4, putting the dried green body into a high-temperature furnace, and carrying out sintering treatment to obtain the refractory ceramic product. Through the method, the synergistic effect of alumina and alumina aggregate can be effectively utilized to prepare the refractory ceramic with high refractoriness, high refractoriness under load, high thermal shock resistance and high corrosion resistance, and the refractory ceramic is suitable for high-temperature heat treatment equipment. According to the method, a slip casting process is adopted, so that the refractory ceramic with a complex shape can be manufactured, and the yield and the production efficiency are improved.
