Silicon carbide ceramic product and non-mold casting method thereof
The invention discloses a silicon carbide ceramic product and a non-mold casting method thereof, and relates to the field of material preparation, and the non-mold casting method can be used for solving the problem that the ceramic product with high surface quality, uniform structure and complicated shapes cannot be prepared by an existing preparation process. According to the main technical scheme disclosed by the invention, the non-mold casting method of the silicon carbide ceramic product comprises the following steps: carrying out mixing and ball-milling on raw materials for preparing the silicon carbide ceramic product, so as to prepare a raw material slurry, wherein the raw materials for preparing the ceramic product comprise silicon carbide, carbon black, a dispersing agent, an organic monomer and water; adding an initiating system to the raw material slurry, and mixing evenly, so as to obtain a ceramic slurry; sequentially carrying out vacuum degassing treatment, injection molding, stripping and drying on the ceramic slurry, so as to prepare a ceramic biscuit; carrying out numerical control machining on the ceramic biscuit, so as to obtain a ceramic perform with a set shape; and sintering the ceramic perform with the set shape at 1500-1800 DEG C, so as to obtain the silicon carbide ceramic product. The non-mold casting method is mainly used for preparing the silicon carbide ceramic product with high surface quality, uniform structure and various complicated shapes.
