additives (AlN, Al2O3 and B4C etc) are commonly adopted to obtain well-sintered SiC ceramic materials. The characteristics, such as shape, microstructure and grain size, of the starting SiC powder and the additive powder, have great influences on the properties of SiC ceramics sintered[1, 5-7]. In the past decades, sol-gel techniques have been utilized to synthesize ceramic composite powders......
