Fabrication of Bulk Ceramics by High-Gravity Combustion Synthesis

摘要：

　　Both single-phase and multiphase bulk ceramics were prepared by high-gravity combustion synthesis via melt solidification instead of conventional powder sintering.The synthesis process included three steps,namely,combustion reaction,phase separation,and melt solidification.In these steps,phase separation played a key role in producing bulk ceramic materials with high purities and low porosities.It was demonstrated that,in a high-gravity field the phase separation was greatly accelerated,compared with the case under common gravitational condition.In comparison with powder sintering,high-gravity combustion synthesis requires no furnace and can reduce the processing time for the fabrication of bulk ceramic materials.
