Author(s): Sivashankari L, Rajkishore SK, Lakshmanan A and Subramanian KS
Abstract: A series of experiments were carried out to optimize key parameters that are associated with dry milling process for synthesizing zeolites in the nano size regime. Milling time and rotational speed in planetary ball milling were the main parameters chosen for optimization. This study revealed that dry milling at 400 rpm for 5 hours resulted in 10-100 nm sized nanozeolites. Further, the morphology, stability and chemical nature of natural zeolite and milled zeolites were characterized using Particle Size Analyzer (PSA), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Energy Dispersive X-Ray Spectroscopy (EDAX), Fourier Transform Infrared (FTIR) Spectroscopy and X-Ray Diffraction (XRD). Overall, the optimized milling process did not change the stability of zeolites, but on the other hand the changes in shape and crystallinity that are associated with top-down approach were observed and discussed in this paper.
