An investigation of aluminosilicate zeolite L (structure code LTL ) nanocrystals converted from rice husk ash in template‐free system is reported. Crystallization evolution of the zeolite L was monitored and followed by X‐ray diffraction, high‐resolution transmission electron microscopy, scanning electron microscopy, atomic absorption spectroscopy, and infrared spectroscopy techniques. It was found that fully crystalline zeolite L ( Si/Al = 3.0) with square tablet morphology was nucleated at 4 h, and the crystals with a mean particle size of 210 nm was completely transformed from amorphous silica after 24 h of hydrothermal treatment.
