Notes:
Single phase Sialon was synthesized successfully from fly ash by carbothermal reductionnitridationreaction in this paper. The effects of synthesizing temperature (1200ºC, 1300ºC, 1400ºCand 1450ºC) and carbon content (stoichiometric content, exceeding 10%, 50% and 100%) on the finalproduction were studied by XRD and SEM. Synthesis mechanism of β-Sialon was also analysized.The results indicated that single phase β-Sialon with z=3 was obtained using fly ash as raw materialsand carbon black of stoichiometric content as reducer by carbothermal reduction- nitridation reactionin flow nitrogen at 1450ºC for 3h. Temperature and content of carbon had significant effect on thesynthesis of β-Sialon
