The Ba-Ge phase diagram in [Massalski2] was redrawn from [Moffatt].

Figure 1 shows the Ba-Ge phase diagram revised by [2008Pan] based on thermal analysis data measured for the range 0-75 at.% Ge. The Ge-rich part was adopted from [2005Car]. This phase diagram is more complex in comparison with the [Massalski2] phase diagram, which showed only four intermediate phases.
