Nano-Grained Microstructure Design of Silicon Carbide Ceramics by SPS Process
SiC ceramics were fabricated from submicron- and nano-sized starting powders with Y2O3 and AlN additives by SPS process. The SPS process and the use of AlN additive were found to be effective for achieving the nano-grained microstructure with retarded grain growth. The nanoporous SiC ceramics were also obtained under the similar conditions. The optimum heating schedule and additive composition were proposed.
