A sintered SiC body is produced by forming a thermoplastically moldable ceramic composition comprised of sinterable silicon carbide powder and binder, thermoplastically molding the ceramic composition into a body, embedding the body in nominally spherical particles having a density greater than 80% of the particle's theoretical density and being selected from the group consisting of polycrystalline silicon carbide, free carbon-coated polycrystalline silicon carbide, free carbon and mixtures thereof, baking the embedded body to remove the binder therefrom, recovering and sintering said baked body. |
