Structural studies on the phase diagram of cerium

The puzzle of the $ \gamma\to\alpha$ and other phase transitions in cerium

“…There, the direct phase transition from the tetragonal phase () to the cubic -phase [25] and the transition in the opposite direction (т.е. ) were found at pressures 7.1 GPa (T735 K) and 7.2 GPa (T800 K) [24,26] (see Fig.1). On the basis of these studies a suggestion on the existence of -'- triple point at 6.9 GPa and 600 К was made [26].…”

Thermodynamic properties and structural phase transition of cerium under high pressure

“…4, we show the obtained temperatures of the γ-Ce→ δ-Ce phase transition as a function of pressure up to 2.4 GPa. The experimental data are also displayed for comparison [23].…”

The magic of plutonium: 5f electrons and phase instability

“…in the most recent pressure-temperature phase diagram of Zhao and Holsapfel [13] in Figure 6). The transformation is an isostructural collapse with an enormous volume decrease of ϳ16 pct.…”

“…[24] With the advent of high-performance computing, it has become possible during the past 10 to 15 years to extend such calculations to the actinides by Fig. 6-The equilibrium pressure-temperature phase diagram for cerium (from Zhao and Holzapfel [13] ). incorporating low-symmetry crystal structures, relativistic effects, and electron-electron correlations.…”
