Effect of crystallization time on preparation of nanozeolite NaA from rice husk

Nanozeolite NaA with crystal sizes ranging from 50 to 120 nm was synthesized by the hydrothermal method with silica extracted from rice husk as its source. The composition of the amorphous extracted silica powder was 87.988 wt% SiO2. The effect of the crystallization time on the properties of the final product was investigated. The synthesized nanozeolite was characterized by XRD and SEM techniques.
