Combustion synthesis of AlN-SiC solid solution particles

The feasibility of synthesising AlN-SiC solid solution ceramics by combusti on synthesis (CS) reaction is demonstrated through igniting the mixtures of aluminum, silicon and carbon black under different nitrogen pressure value s. The effects of the nitrogen pressure and the atomic ratio of (Si + C)/Al on the crystalline phases formed in the reaction product and on the charac teristics of combustion behaviour were investigated. Combining thermodynami c analysis and the combustion characteristics, the reaction sequence and th e formation of AlN-SiC solid solution by CS were explained. (C) 2000 Elsevi er Science Ltd.
