| Abstract: | The feasibility of synthesizing AlN-SiC solid solution ceramics by combustion synthesis reaction is demonstrated through igniting the mixtures of aluminum, silicon, carbon black under difFerent nitrogen pressure. The effects of the nitrogen pressure and the ratio of Al/Si+C on the phase formation of product and the characteristics of combustion behavior were investigated. Combining thermodynamic analysis. the reaction sequence and reason for CS AlN-SIC solid solution were explained. |
