Investigation of parameters affecting zeolite NaAcrystal size and morphology

Crystal size and morphology of zeolite NaA have an important role in its specific use in the industries. Thus, investigation of parameters which influence crystal size and morphology of this compound during the synthesis is very important. Parameters such as intensi ty of mixing, temperature and aging time of the gel preparation, crystallization temperature and composition ratios are I"m portant I"n t hI"S case.
