Comparative study of natural calcium stilbite and magnesium exchanged stilbite for ethanol sensing

Journal of Porous Materials, 2012
Natural stilbite (Ca-stilbite) zeolites have been collected from the queries near Pashan area, Pune, Maharashtra, India. The calcium ions in the Ca-stilbite structure are partially exchanged by magnesium ions using ion exchange process. The Ca-stilbite and Mg- stilbite samples are characterized by XRD, EDS, FTIR and TG/DTA techniques and are used as ...

Thermal decomposition of the natural zeolite stilbite

Zeolites, 1985
Abstract Based upon results of differential thermal analysis (d.t.a.) measurements, the natural zeolite, stilbite, from Rožsinka (Moravia, Czechoslovakia) was subjected to isothermal decomposition at temperatures of 20°, 200°, 260°, 470°, 550°, 620°, 770°, 870° and 1000°C.

The Morphology of Hydrothermally Synthesized Stilbite Type Zeolites

Journal of Solid State Chemistry, 1999
Abstract Stilbite, stellerite, and barrerite—zeolites having the stilbite framework—were synthesized in a temperature range between 200 and 250°C by hydrothermal conversion of artificial water-free precursor glasses of the respective same composition at 1 kbar H2O pressure.

Phase transition at thermal dehydration in stilbite

Journal of Thermal Analysis and Calorimetry, 2011
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.

Rehydration of heulandite and stilbite

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1988
1. Stilbite and heulandite begin to undergo sintering upon heating in vacuum at 200 ± 5°C and undergo about 80% dehydration. 2. The rehydration energy (heat of immersion in water) of stilbite and heulandite reach maximal values of 350 ± 15 and 215 ± 15 J/g after pumping at 230 ± 20 and 200 ± 20°C, respectively.

Thermodynamic properties of the zeolite stilbite

Zeolites, 1990
In this study, calorimetric measurements of the molar enthalpy of formation Δ f H 0 m at 298.15 K, molar heat capacity C 0 p,m (and, thus, the molar entropy 7 S 0 m ) from 5 to 350 K, and enthalpy increments H 0 m ( T ) — H 0 m (298.15 K) from 350 to 500 K were performed on a specimen of stilbite characterized by electron ...

Thermal behaviour of natural stilbite crystals

Thermochimica Acta, 1982
Abstract Observations of the behaviour of natural stilbite crystals on dehydration are reported. Results of TG, DTA, static weight loss measurements, X-ray diffractometric analysis and IR studies are described and interpreted. It is established that the stilbite structure collapses at about 400°C.
