【 摘 要 】

A novel process for increasing �?-SiC yield on solid state reaction of coal fly ash and micro powder activated carbon powder has been proposed. �?-SiC powder was synthesized at temperature 1300°C for 2 h under vacuum condition with 1 l/min argon flow. Cycling synthesis process has been developed for increasing �?-SiC yield on solid state reaction of coal fly ash and activated carbon powder. Synthesized products were analyzed by XRD with Cu-K�? radiation, FTIR spectrometer and SEM fitted with EDAX. The results show that the amount of relative �?-SiC is increased with the number of cycling synthesis.
