【 摘 要 】

Zeolite NaY (FAU) has been prepared through direct hydrothermal method by using Sodium Silicate and Colloidal Silica as the silica source. Aging time was carried out at 24 hours while hydrothermal temperature was performed at 90°C for 24 hours. Detailed comparisons and characterizations were performed by using several methods onto the synthesized zeolite NaY (FAU) by using powder X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM) and Energy dispersive X-Ray spectroscopy (EDX). The results showed that the products obtained from the starting gel were highly dependent on the type of raw material used-silica source which affects the structure of the products.
