摘要

The Zeolite W synthesized from coal fly ash(CFA)by hydrothermal method using 5 M Kalium hydroxide(KOH),variations of KOH: CFA ratio(1,2 and 3 L/kg)and hydrothermal temperature(150,200,and 250°C)for 8 hours had been done.The XRD diffractogram analysis revealed five peaks at 26 around 10.61°;12.48°;27.39°;28.19°;and 32.92° which correspond to the peaks characteristic of zeolite W.The refinement result showed the other phases such as hematite,quartz,and tobermorite.
