Microstructure evolution of ceramic materials during solidification from melts in high-gravity combustion synthesis

► Bulk ceramics can be prepared via melt solidification by high-gravity combustion synthesis. ► Most ceramic materials undergo a faceted crystal growth mode. ► A strongly textured layer occurs at the surface of Al2O3 samples. ► Eutectic ceramics show a fine microstructure with submicron interphase spacings.
