摘要：

Pure high silica KFI-type zeolite samples with a framework Si/AI molar ratio as high as 4.0 were prepared by using 18-crown-6 ether as an organic template from a starting aluminosilicate gel containing potassium and strontium cations, The solids were characterized by elemental analysis, SEM, XRD, thermal analysis, solid state n.m.r. spectroscopy, and n-hexane adsorption. The 18-crown-6 ether is occluded in the structure (one molecule/unit cell), its presence allows reproducible preparations of highly crystalline materials with high Si/Al ratios.
