Ga-Na (Gallium-Sodium)

Table 0 Cmca I 0 /mmm Pnma Im 0 m 0 0 Composition, at.% Na Phase - The Ga-Na phase diagram in [Massalski2] was redrawn from [1990Pel]. Based on essentially the same phase boundary data as [1990Pel], [2007Wan] calculated the Ga-Na phase diagram, as shown in Fig. 1. The melting reaction of Ga4Na was a congruent type in [1990Pel]. The peritectic type shown in Fig. 1 is likely because it requires a more symmetric peak in the liquidus boundary around Ga39Na22 [1991Oka]. The peak of the miscibility gap on the Na-rich side was estimated to be around 550 C in [1990Pel], which is very much lower than the calculated value in Fig. 1. Experimental data are not available for confirmation of either value. Ga-Na crystal structure data References Pearson symbol Space group Strukturbericht designation (...truncated)
