Inert Gas Crystals

  1. Sep 11, 2005 #1
    I am in search of physical properties of inert gas crystals ( such as colour,lustre,etc). I could get only the melting point.

    Specifically, i want for Neon, Argon, Krypton and Xenon which are fcc.

    I looked at various sources and could find the following which were most comprehensive.

    Melting Pt: 115.93K -157.22°C -251°F

    Melting Pt: 161.5K -111.7°C -169.1°F

    Since the gases are colorless as gas, unless in an electrical discharge, i.e. ionized, they presumably would be colorless as a solid.

    Possibly Praxair or BOC might have the properties if they supply those gases.

    I don't know if anyone does solid noble gases.

    Thanks, Astronuc for those links !

    I am doing a project to find out the Bulk Modulus and Energy variation of Inert Gas Crystals using Lennard-Jones Potential . So wanted to quote some simple properties of inert gas crystals in the introduction part.

    all at 0 Kelvin . Now i have got the value for cell constant ( lenght of the crystal cube ) at 0K and 0 pressure and cohsive energy at 0 k and 1 atm, that is what is itching me right now.


    In charles kittel he has given the value of cell constant extrapolated at 0K and 0 Presure and in oneother book by stephen eliot has the value at 4 K. I want things at 0 K , so that there are no thermal vibrations and it remains simple.

    I need cell constant at 0 K and 1 atm if given in any other solid state book or on net or in any data book.

    Have you tried looking in the CRC Handbook?

    Data at 0 K might be a challenge. That is pretty esoteric.

    I was also thinking that if it is colorless, and the electron shells are filled (noble gas), then the solid should be pretty transparent.

    You might find the data in a CRC book - Handbook of Chemistry and Physics - as ZapperZ suggested. If you don't have access to one, I can look, but you should perhaps find it in a library, or Chemistry or Physics department.
