Na-Ga metal miscibility

He tried to dissolve Na in liquid Ga and failed. One condition he didn't test is the miscibility when both metals are liquid. Can anyone test this?

They look almost completely insoluble in each other below 300 oC.

The neat thing is that it should be possible to grow crystals of sodium from gallium by making a solution at about 550°C and slowly cooling. This is quite achievable with a glass annealing oven and suitable crucible.

No, because there's solid alloys forming, as well.

Praxi's idea of growing crystals of sodium from slowly-cooling gallium solutions.
