We compare the liquid-gas phase diagram of metals in NH3 with electron-hole liquids and doped semiconductors. Both the metal:NH3 and e-h liquid-phase diagrams are asymmetric compared to those of simple fluids. The asymmetry appears to result from changes with density in the range of interaction between the positive and negative species, as emphasized by Mott, although the metal-insulator transition may be at zero temperature, as in Si:P.
