Nanosized EMT-type zeolite crystals with a diameter of 15 nm are synthesized from a precursor suspension free of organic template using rice husk ashes (RHA) as a silica source. The crystallization process of the EMT-type zeolite is accomplished within 28 h at 28 °C. The fully crystalline EMT-type zeolite nanoparticles have equilateral hexagonal shape, Si/Al ratio of 1.28 and high crystalline yield of 75%.
