In this study, effects of gel formulation parameters such as Na2O/K2O molar ratio(from 0.05 up to 3) and tetra methyl ammonium hydroxide (TMAOH) additive in the synthesis of zeolite T (Linde Type T) crystals have been investigated in different SiO2/Al2O3 molar ratios from 5 to 29. Submicron and nanosize crystal of zeolite T from 100 nm up to 25 µm with distinctive crystal shapes from the needle type to cylindrical crystals have been synthesized successfully at the wide range of SiO2/Al2O3 ratios with and without TMAOH. It is shown that Na2O/K2O ratio plays the most important role in gel formulation. All synthesized crystalsare characterized by XRD and SEM analysis.
