High pressure melting of wüstite
Iron oxide (FeO) is an important component in the mineralogy of Earth's lower mantle, and possibly its core, so its phase diagram is essential to models of the planet's interior. The melting curve of wüstite, Fe0.94O, was determined up to 77 GPa and 3100 K in a laser-heated diamond anvil cell. Melting transition temperatures were identified from discontinuities in the emissivity vs. temperature...
متن کاملHigh-pressure melting curve of hydrogen.
The melting curve of hydrogen was computed for pressures up to 200 GPa, using molecular dynamics. The inter- and intramolecular interactions were described by the reactive force field (ReaxFF) model. The model describes the pressure-volume equation of state solid hydrogen in good agreement with experiment up to pressures over 150 GPa, however the corresponding equation of state for liquid devia...
متن کاملMelting Temperature Depression of Solid Lipid under High Pressure Gases
The effects of high pressure gases on solid lipids were investigated by high-pressure differential scanning calorimeter (DSC). In particular, the influence of a high-pressure gas on solid-liquid and solid-solid transitions were investigated for pure tristearin and a mixture of lipids (tristearin-phosphatidylcoline-dioctilsolfosuccinate). Both of these substances are commonly used for the produc...
متن کاملMelting of ice under pressure.
The melting of ice under pressure is investigated with a series of first-principles molecular dynamics simulations. In particular, a two-phase approach is used to determine the melting temperature of the ice-VII phase in the range of 10-50 GPa. Our computed melting temperatures are consistent with existing diamond anvil cell experiments. We find that for pressures between 10 and 40 GPa, ice mel...
متن کاملMelting curve and fluid equation of state of carbon dioxide at high pressure and high temperature.
The melting curve and fluid equation of state of carbon dioxide have been determined under high pressure in a resistively heated diamond anvil cell. The melting line was determined from room temperature up to 11.1+/-0.1 GPa and 800+/-5 K by visual observation of the solid-fluid equilibrium and in situ measurements of pressure and temperature. Raman spectroscopy was used to identify the solid ph...
