Zeolite A (LTA) was synthesized with two compositions,using tetramethylammonium hydroxide as templating agent,tetraethyl orthosilicate as silica source and aluminum iso-propoxide as alumina source.The samples were characterized by X-ray powder diffraction analysis(XRD).It is evident from XRD, LTA is formed successfully and the width of peaks are broad.It is expected from these vast peaks,these particles are in nano size.
