Ge-Na (Germanium-Sodium) Editor The Ge-Na phase diagram is redrawn from [82Dri] ranging from 50 to 100 at.% Na. The 0 to 50 at.% Na range has been drawn schematically based on [89Pot], who reported Ge4Na melting at 1146 C.Ge4Na was not shown in the diagram of [82Dri] and accordingly the liquidus of GeNa was unusually asymmetric. The two eutectics on both sides of Ge4Na are tentatively shown at 930 C, based on more than four thermal arrest data points on each side reported by [82Dri], who considered all points to correspond to the L = (Ge) + GeNa eutectic temperature. Probably, the eutectic temperature on the Na-rich side is lower, as in the cases of the Ge-K, Ge-Rb, and Ge-Cs systems.--H.O. 61Sch: R. Schafer and W. Klemm, Z. Anorg. Allg.
