| Abstract: | Using calcined stilbite, aluminium hydroxide and sodium hydroxide as ingradients, the procedure to synthesize a zeolite by hydrothermal method is described. Studies on characterisation (of crystals grown) by X-rays and by infrared spectroscopy, and their morphology by a scanning electron microscope are reported. That the crystals grown have cubic symmetry with a = 13.66 Å and that they are analcime type is established. From infrared spectral studies it is confirmed that the crystals are zeolites. Needle, prismatic, and layer crystals obtained are illustrated and described. |
