Abstract

Thermal dehydration of stilbite was investigated by thermogravimetry and in situ X-ray powder diffraction. Sample mass changes continuously over the whole temperature range, with anomaly near 175 °C described in terms of the second-order phase transition with changes in symmetry from F-centered unit cell to A-centered one. This contradicts to the step-wise change in sample mass and the first-order phase transition with symmetry changing from F2/m to Amma reported in literature. The change in the order of the phase transition by means of the changes in experimental techniques is discussed.
