Crystallization pressure

  1. Jun 24, 2014 #1
    Given an unknown fluid, what would be an efficient and/or cheap way of finding it's crystallization pressure through experiment.

    I would like to keep costs at a minimum and work from off the shelf components if possible.

    Hi kubedgamer,

    A seemingly cheap setup is described here:
    http://www.igsoc.org/journal.old/10/59/igs_journal_vol10_issue059_pg312-315.pdf [Broken]

    When you say unknown liquid, it could mean that a given setup will be easily inadequate by the virtue of the liquids unknown melting point and overall behavior.

    Hi Lok,

    Thanks for your reply.

    I saw that paper earlier, unfortunately they're focusing on finding the pressure exerted by freezing ice against an obstacle.

    "Polycrystalline ice, growing from the melt, can exert a pressure against an extended obstacle,
    even though it is free to grow in other directions. Pressures of over 0.2 bar (20kl m-z) have been measured
    with simple apparatus. This phenomenon may be important in explaining the frost-shattering of rocks"

    Unfortunately, not what I'm after :(

    So you would like to find... the pressure at which the unknown liquid freezes?

    That's correct :)

    In this case I cannot imagine something cheaper than the obvious anvil cell.
