Phase diagram of oxygen. Oxygen - Thermophysical properties The oxygen phase diagram shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the oxygen boiling point with changes in pressure. It also shows the saturation pressure with changes in temperature. Phase Diagrams - Chemistry A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature, and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points).

Collective spin 1 singlet phase in high-pressure oxygen Oxygen, one of the most common and important elements in nature, has an exceedingly well-explored phase diagram under pressure, up to and beyond 100 GPa. At low temperatures, the low-pressure antiferromagnetic phases below 8 GPa where O 2 molecules have spin S = 1 are followed by the broad apparently nonmagnetic ε phase from about 8 to 96 GPa.

Phase diagram of oxygen on Ni(100) — Northwestern Scholars Abstract. We have studied the coverage-temperature phase diagram of chemisorbed oxygen on Ni (100) with LEED and AES. We find that the oxygen p (2 × 2) structure undergoes a nearly reversible order- disorder phase transition for coverages between 0.15 and 0.30 monolayer (T c ≈ 560 K for θ = 0.25). For these coverages, it is also found that the chemisorbed oxygen begins dissolving into the bulk nickel as the overlayer disorders.
