Influence of Adding β-SiC on the Performance of α-SiC Pressureless Sintering Ceramics

摘要：

　　The B4C and phenolic resin were used as sintering additives to study the different β-SiC (cubic silicon carbide) addition to the performance of α-SiC pressureless sintering ceramics in this paper,and the optimum sintering temperature and the best β-SiC addition amount were determined.By XRD,SEM,density testing and other tests showed that,all the β-SiC transform 6H α-SiC during the sintering process,the ceramics have a Vickers hardness of 18.04 GPa,a fracture toughness of 4.51MPa,a density of 3.13g/cm3 by adding 15wt% β-SiC powders.
