In the present article, the effect of various parameters on synthesis, crystal size, morphology and
hydrothermal stability of zeolite β are discussed. The most important parameter is Si/Al ratio and scrutinized
widely. The effect of Si/Al ration in precursor gel on crystal size and crystallinity, effect of hydrothermal
treatment on structure and acidity and industrial stability of zeolite β is reviewed. The Presence of organic
template molecules and effect of seeding on structure, physical and chemical properties of zeolite β is also
mentioned. Results of a new two-stage varying temperature synthesis and supercritical fluid aided
crystallization which is published recently to obtain high yield of nanocrystalline zeolite β is also presented.
