The structure of eutectic composites consists of coupled single crystals, and their properties are expected to differ from conventional composites. Eutectic ceramics composites are fundamentally prepared form melt. The melting point of heat-resisting ceramics is near 2000℃. Unidirectional solidification is adopted to form eutectics without pores and cracks. The size and shape of the unidirectionally solidified are restricted, and not applied to complex large parts. The spark plasma system (SPS) makes it possible to consolidate materials in electric field. The eutectic powder prepared from solid was consolidated by SPS. Eutectic structure was reproduced, coupled crystals being joined each other and grown.
