Fig. 2: Convex hull of La-Co-Pb system.

From: Machine learning guided discovery of ternary compounds involving La and immiscible Co and Pb elements

Fig. 2

Calculated convex hull of the formation energies in the La-Co-Pb system: a based on previously reported phases and b after including the predicted La3CoPb phase. All calculations were carried out at 0 K. Black solid circles in the ternary phase diagram represent stable compounds and the green solid star represents a predicted stable phase, while blue hollow triangles indicate the metastable ternary phases. The black lines separate the composition space into Gibbs triangles.
