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 ...
ON THE H-FORM OF NATROLITE

Likhacheva A.Yu.; Belitsky I.A.; Veniaminov S.A.; Paukshtis E.A. (2006)

To resolve the problem of existence of the H-form of natrolite, the thermal decomposition of NH4-exchanged natrolite (as a precursor of the H-form) was studied by gas chromatography, IR spectroscopy and X-ray diffraction. ...
