Reaction sintered SiC usually contains 8% free Si. Therefore, in order to ensure complete Si infiltration, the blank should have sufficient porosity. Generally, by adjusting the initial mixture - The content of SiC and C, - The particle size distribution of SIC, C no nsusuwii ne ne kɛse, ne nsusuwso nhyɛso no betumi adi dwuma de anya green density a ɛfata.
