Solid-Liquid-Gas Phase Diagram of Palmitic Acid + Carbon Dioxide SystemFrancisco J. VerónicoSánchez
(T) for anyx,P, andTof the system. Crystal growth, therefore, requires precise knowledge of the solid, liquid, and gasexistence regionswith respect to temperatureT, pressureP, and compositionx(Triboulet, 2005). The works carried out by Greenberg provide accurate data for such stoichiometric ...
Consider the phase diagram for carbon dioxide shown in Figure 5 as another example. The solid-liquid curve exhibits a positive slope, indicating that the melting point for CO2increases with pressure as it does for most substances (water being a notable exception as described previously). Notice t...
摘要: Measurements and theoretical estimates are presented of the liquid-gas phase diagram of an electron-hole fluid in pure germanium. The critical point is found to occur in a region where the fluid is an electron-hole plasma at T=6.5+/-0.1 K and n=(8+/-2)×10cm....

The authors present the liquid-solid phase diagrams that they mapped with a differential scanning calorimeter (DSC) for the following seven binary carbonates: dimethyl carbonate (DMC)-ethylene carbonate (EC), ethyl methyl carbonate (EMC)-EC, EMC-propylene carbonate (PC), EMC-dimethyl ethylene carbo...
gas will not change into a liquid or a solid.Let’s call this critical temperature point TC, so there won’t be a full phase change.There will be a change in its properties, however.It won’t behave like a gas anymore.It will have the properties intermediate between the liquid and ...
Establishing the phase diagram of hydrogen is a major challenge for experimental and theoretical physics. Experiment alone cannot establish the atomic structure of solid hydrogen at high pressure, because hydrogen scatters X-rays only weakly. Instead, our understanding of the atomic structure is largely...
The equilibrium phases encountered in the phase diagram of the Zr–Al system (Massalski et al. 1992) shown in Figure 1.14 are: the liquid (L); the bcc (β-Zr) and the hcp (α-Zr) solid solutions, the ten intermetallic phases, Zr3Al, Zr2Al, Zr5Al3, Zr3Al2, Zr4Al3, Zr5Al4, ...
