K-F zeolite nanocrystals (structure code EDI) are synthesized from a template-free Al2O3eSiO2eK2O
eH2O precursor system. The use of a very reactive organic-template-free gel system (4SiO2: 1Al2O3:
16K2O: 160H2O) enables the crystallization of EDI-type nanosized zeolite to accomplish within 3 h at
100 C. The K-F zeolite crystals have flattened cuboid shape morphology (ca. 27 nm) and they tend to
agglomerate and form secondary spherical particles (ca. 310 nm). The K-F zeolite nanocrystals have high
alumina content (Si/Al ratio ¼ 1.10) and high crystalline solid yield (79%) offering a promising route for
large-scale production of hydrophilic zeolite nanoparticles.
