The invention discloses a silicon carbide ceramic perform, an aluminum-based silicon carbide ceramic material, and a preparation method of same, and relates to the technical field of materials and preparation methods thereof. The invention solves the technical problems of low strength and non-uniform structure and low volume percentage of silicon carbide of silicon carbide ceramic performs in the prior art. In a main technical scheme, the preparation method includes the steps of: 1) uniformly mixing raw materials for producing the silicon carbide ceramic perform to obtain raw material slurry, wherein the raw materials include: silicon carbide, a dispersant, an organic monomer and water; 2) adding an initiator to the raw material slurry, and uniformly mixing the components to form ceramic material slurry; 3) successively performing vacuum degassing treatment, injection moulding shaping, demoulding and drying to obtain a ceramic green body; 4) sintering the ceramic green body at 800-1200 DEG C to form the silicon carbide ceramic perform. The preparation method is mainly used for preparing the silicon carbide ceramic perform which has high strength and uniform structure, and further preparing the high-performance aluminum-based silicon carbide ceramic material.
