Journal Article
Structure and elastic properties of quartz at pressure
TL;DR: In this paper, unit cells and crystal structures were determined on a single crystal of quartz at seven pressures from I atm to 61.4 kbar by fitting the P-V data to a Birch-Murnaghan equation of state.
Journal ArticleDOI
Elasticity of α-Cristobalite: A Silicon Dioxide with a Negative Poisson's Ratio
TL;DR: In this paper, the adiabatic single-crystal elastic stiffness coefficients of silicon dioxide (SiO 2 ) in the α-cristobalite structure were determined using laser Brillouin spectroscopy.
Journal ArticleDOI
The deformation-DIA: A new apparatus for high temperature triaxial deformation to pressures up to 15 GPa
TL;DR: In this article, a deformation apparatus based on the widely used cubic-anvil apparatus known as the DIA is developed, which allows independent control of the differential strain and stress field under high confining pressure.
Journal ArticleDOI
Single‐crystal elastic properties of the spinel phase of Mg2SiO4
TL;DR: In this article, the elastic properties of the spinel and modified spinel (beta) phases of Mg2SiO4 are quite similar with the greatest differences related to the c axis of the beta which is relatively soft under compression.
Journal ArticleDOI
The single‐crystal elastic moduli of stishovite
TL;DR: In this article, the single-crystal elastic moduli of stishovite have been determined experimentally from measured Brillouin scattering spectra and the estimated aggregate (Voigt-Reuss-Hill) adiabatic moduli are K = 3.16 ± 0.04 in units of mbar.
