Thank you very much Agustin sir for helping me..

Yes, the other link is more useful to me I found more useful data of that pdf file.

There are many parameters going to affect during the hydrothermal synthesis of zeolite. An effect of time, temperature, stirring and aging properties were also conclude for maintain the proes of zeolites. Kumar et al also reported for various parameter optimized for zeolites. even after synthesized material the calcinations temperature rate also alter ther pore size parameter. it create single pore to bimodal pores through high temperature rate. threre we can seen in BET isotherm of unusuall pore size, hence low and slow heating rate also aviod such colapsed of pores in zeolite.

There are two "types" of pores sizes: the structure pore size and the practical pore size. In the first case, the pore size as well as its topology, is dictated by the way in which the TO4 tetrahedra (T= Si, Al, metals, etc.) are connected and this is ultimately commanded by the structure directing agent (organic or inorganic). The practical pore size is the one really available for the adsorbing molecules. It can be affected by the framework counterions (nature, size and population), degree of dehydration (or desolvation) and presence of previously strongly adsorbed species among others.

This question cannot be answered concisely, because all operating conditions during a given hydrothermal synthesis process play keyroles on the pore size of zeolites, more particularly the Si:Al ratio (or other ratios for pseudozeolites), pH, temperature and synthesis procedures (template, if any, contact time, nature of reagents, OH- amount in alkaline media, F- or other for acidic media,...). The pore size strongly depends on the zeolite framework, and thereby on the chemical composition of the starting reactant mixture. A more precise question will be easier to elucidate.

I agree with Abdelkrim, source of Si, media, use of SDA (structure directing agent), treatment time, temperature, stirring or static condition, cancination are have be optimize to get desired one.

yes i agree the pore and structure of zeolites optimized by gel compositions, temperature and nucleation time like to be set as univarient in phase rules. All these parameters set on the particular coditions maintain that specified zeolites. appart from that, choice of templates also resides the pore size, but not significant role of mineralizes such as OH- ion in alkaline and F- ion in fluoride medium synthesis. its just improve the solibility of T ions. However, zeolite crystal growths altered with effect of neculiation times, reflects in alkaline media synthesized zeolite extend its time we can see the mordinite phase or glassy phase additionally we can see it. therefore them textural properties were also ultimatly change.

Thank you all four your comments and recommendation.
