The thermal transformation of Ba exchanged zeolite X to celsian has been studied by 27 Al and 29 Si MAS NMR spectroscopy. Evidence for the degradation of the zeolite framework is present in the 29 Si NMR spectra after thermal treatment at 850 1C. Confirmation is provided by the 29 Si NMR data that s
