A novel process for increasing β-SiC yield on solid state reaction of coal fly ash and micro powder activated carbon powder has been proposed. β-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 β-SiC yield on solid state reaction of coal fly ash and activated carbon powder. Synthesized products were analyzed by XRD
with Cu-Kα radiation, FTIR spectrometer and SEM fitted with EDAX. The results show that the amount of relative β-SiC is increased with
the number of cycling synthesis. 相似文献
