There has been substantial renewed interest in negative thermal expansion following the
discovery that cubic ZrW 2 O 8 contracts over a temperature range in excess of 1000 K …

Anomalous thermal expansion behaviour of several open frame-work compounds has been
extensively investigated using the techniques of inelastic neutron scattering and lattice …

High pressure Raman spectroscopic studies are carried out on negative thermal expansion
material ZrW 2 O 8. The system exhibits amorphization at 2.2±0.3 GPa via an intermediate …

We present an x-ray pair distribution function (XPDF) analysis and extended x-ray
absorption fine structure (EXAFS) data for ZrW 2 O 8 (10–500 K) with a focus on the stiffness …

Isotropic negative thermal expansion has been reported in cubic ZrW 2 O 8 over a wide
range of temperatures (0–1050 K). Here we report the direct experimental determination of …

We measured zirconium tungstate's elastic constants C ij. This compound shows relatively
soft, nearly isotropic elastic constants with normal Poisson ratios and no approach to Born …

Mode Grüneisen parameters were estimated for α-ZrW 2 O 8 zone-center modes by means
of density functional theory calculations and the temperature dependence of the coefficient …

An infrared study of the phonon spectra of Z r W 2 O 8 as a function of temperature which
includes the low-energy (2–10 meV) region relevant to negative thermal expansion is …

The ZrW2O8 family of materials has been shown to display the unusual property of an
isotropic bulk contraction in volume as a function of temperature. We report here on negative …

In order to investigate the relationship between negative thermal expansion and other
thermal properties, the thermal conductivity of the α-phase of ZrW2O8 has been determined …
