The Mg-Sb phase diagram in [Massalski2] was redrawn from [1984Nay].

[1990Oka] pointed out an unlikely feature in this phase diagram, i.e., the metastable melting point of αMg3Sb2 cannot be defined uniquely when extrapolated from the liquidus curves on the Mg-rich and Sb-rich side unless thermodynamically unlikely sudden change of curvature is introduced in these liquidus curves.

Figure 1 shows the Mg-Sb phase diagram calculated by [2009Pal]. Naturally, the problem described above is solved in this figure.
