Fig. 3: Calculated isothermal phase diagram of the Pr-Ir-O2 system with gas phase included.

A single point represents the stable condensed phase, the line connecting two points represents the coexistence of the two corresponding phases, and the triangular area connected by three points indicates three-phase invariant equilibria. In the three-phase equilibrium regime around the right bottom corner, the dominant gas species is O2(g) with other gas species plotted in Supplementary Fig. 1.
