Effect of Different Silica Source on NaA Nanocrystal

Article Preview

Abstract:

Effect of different silica source on the products of NaA nanocrystal was studied. The crystallinity, Si/Al and morphology of samples were characterized by XRD, EDX and SEM. The results showed that the samples using different silica sources have significant difference. The sample using silica sol as silica source have a better crystallinity with Si/Al ratio 1.37 and the particle size were between 100 to 500nm; The sample using TEOS as silica source have a less crystallinity with Si/Al ratio 1.15 and the particle size were between 50 to 120nm.
