| titleOfInvention | Preparation method of high-strength silicon carbide porous ceramic |
| abstract | The invention discloses a preparation method of a high-strength silicon carbide porous ceramic. Raw materials are composed of 98%-99% of mixture of alpha-silicon carbide powder and beta-silicon carbide powder, 0.1%-1.0% of aluminum diboride and 0.5%-1% of polycarbosilane, by weight percent. The method comprises the following steps: 1) adding the raw materials into an organic dispersing solvent, ball-milling, mixing and drying; 2) dry-pressing and forming the obtained silicon carbide compound powder under the 45-55 MPa; and 3) placing a silicon carbide blank into a vacuum pressure-less sintering furnace, for sintering at two steps, thereby obtaining the high-strength silicon carbide porous ceramic. The preparation method is simple and the prepared silicon carbide porous ceramic is characterized by high mechanical strength, suitable porosity, and the like. |
