Solid-phase-sintered Silicon Carbide Article and Preparation Method thereof
The present application relates to the field of engineering ceramic materials, and specifically discloses a solid-phase-sintered silicon carbide article and a preparation method thereof. A method for preparing a solid-phase-sintered silicon carbide article includes the following steps: grinding of raw materials: mixing a micron-scale silicon carbide powder with a boron-containing sintering aid and wet grinding to obtain a slurry; spray granulating: adding a water-soluble carbon black and a binder to the slurry, stirring evenly, and spray granulating to obtain a granulated powder of silicon carbide; mixing; ageing: ageing the wet powder obtained by mixing to obtain a aged material; post-processing: subjecting the aged material to pugging, extruding, drying and heating.
