Electrical Conductivity of Lithium at Mbar Pressures
We report measurements of the electrical conductivity of a liquid alkali metal lithium at pressures up to 1.8 Mbar and 4-fold compression, achieved through shock compression experiments. We find that the results are consistent with a departure of the electronic properties of lithium from the nearly free electron approximation at high pressures, and with ionic pairing correlations in the Mbar re...
متن کاملFluids at high pressures and temperatures
With high pressures, supercritical fluids can be studied over a very wide range of density. Fluids with strongly interacting polar molecules for example water are of particular interest. Results for several thermophysical properties are discussed. Density, dielectric constant and self—ionization of water have been determined or predicted to 1000 °C. Beyond 20 GPa very hot water appears to becom...
متن کاملNew phases of N2O4 at high pressures and high temperatures
High P–T studies of molecular N2O4 using Raman, synchrotron infrared, and X-ray diffraction measurements reveal several new phenomena. Significant changes in the vibrational spectra indicate a phase transition at about 12 GPa. The X-ray diffraction measurements show that the material remains cubic through the transition. We ascribe the transition to a change in the molecular geometry of N2O4 wi...
