Preparation and Characterization of Nanozeolite NaA from Rice Husk at Room Temperature without Organic Additives

Nanozeolite NaA was synthesized by the hydrothermal method with silica extracted from rice husk as silica source. Amorphous silica with 87.988 wt%  SiO2 was extracted from rice husk ash by a suitable alkali solution. The effect of the crystallization time and the ratio of Na2O/SiO2 on the properties...
