Abstract: The large single crystals of silica-rich, Ti-, B-ZSM-5 type zeolitescalled Titanozeosilite and Borozeosilite were synthesized in non-alkaline medium inthe presence of fluoride. The mechanism of the crystallization for the singlecrystals was investigated in the systems of SiO2-TiO2-(TPA)2O-NH4F-H2O and SiO2-B2O3-(TPA)2O-NH4F-H2O.
