Single-crystal elastic constants of the zeolite analcime measured by inelastic X-ray scattering

Lethbridge ZAD, Walton RI, Bosak A, Krisch M

The single-crystal elastic moduli of the zeolite analcime, vertical bar Na-16(+)(H2O)(16)vertical bar[Al16Si32O96] (structure type ANA), have been determined by inelastic X-ray scattering (IXS). The room temperature values (GPa) are C-11=103.5 +/- 5, C-44 = 30.3 +/- 2, C-12 = 21.7 +/- 2. The results demonstrate the applicability of this technique for measuring elastic constants of open three-dimensional structures that include extra-framework species. (C) 2009 Elsevier B. V.
