BEHAVIOR OF H2O MOLECULES IN THE CHANNELS OF NATROLITE AND SCOLECITE: A RAMAN AND IR SPECTROSCOPIC INVESTIGATION OF HYDROUS MICROPOROUS SILICATES

Kolesov B.A.; Geiger C.A. (2006)

Single-crystal polarized Raman spectra (80 to 4000 cm-1 at 4 ≤ T ≤ 700 K) and powder IR spectra (1500 to 4000 cm-1 at 50 < T < 300 K) were measured for two microporous zeolites natrolite, Na16[Al16Si24 O80]·16H2O, and ...
DEHYDRATION DYNAMICS OF BA-PHILLIPSITE: AN IN SITU SYNCHROTRON POWDER DIFFRACTION STUDY

Sani A.; Cruciani G.; F.A. (2002)

The stepwise dehydration process of the Ba-exchanged form of the zeolite phillipsite was studied by in situ synchrotron X-ray powder diffraction. A series of structure refinements were performed using the Rietveld method ...
POZZOLANIC REACTIVITY OF ZEOLITIC ROCKS FROM TWO DIFFERENT CUBAN DEPOSITS: CHARACTERIZATION OF REACTION PRODUCTS

Martínez-Ramírez S.; Blanco-Varela M.T.; Ereña I.; Gener M. (2006)

Volcanic pozzolans are vitreous or poorly crystallized materials rich in SiO2 and Al2O3 that react with the portlandite generated during cement hydration to yield hydrated calcium silicates and aluminates with low solubility ...
