The release of interlayer water followed by the dehydroxylation of hydroxide layers and decomposition of interlayer carbonate anions were observed during samples heating. Thermal decomposition of samples was accompanied by the sharp increase of surface area and radon release rate, which then decreased with increasing temperature as crystallization of formed oxides took place. The ETA results were in a good agreement with results of thermal analysis (TG, DTA, EGA), X-ray diffraction and BET surface area measurements.
