Abstract

The interaction between sodium atoms (obtained by thermal decomposition of NaN3) and acidic OH groups of the zeolite, leading to the elimination of H+ ions, is accompanied by the occlusion of the NaN3 in the zeolitic framework. This salt occlusion process was investigated using X-ray, thermogravimetric, i.r. and visible spectroscopic methods. NaN3 occluded in the zeolite framework does not decompose at 773 K, though this temperature is higher than the decomposition temperature of the pure NaN3. It was found that nearly two N-3 ions per u.c. were occluded in the framework without destroying the crystal structure of the zeolite.
