Backwards phase transitions?

  1. Jan 16, 2015 #1
    Are there any chemicals that are liquid under high pressure (above 1 atmospheres) but solid when exposed to low pressures (below 1 atmosphere)? Are there any chemicals that have a similar reverse phase transition at any pressure with the solid extending down to vacuum?

    "Reverse phase transition?" Not really clear what you mean.

    As in having a liquid phase at a higher pressure than the solid phase while temperature is held steady.
