Abstract

The commercial distribution of liquid neon, an inert cryogenic fluid with a boiling point of 27.2°K, began in 1960. The slow but steady usage growth since that time is due to three basic advantages possessed by liquid neon:
  1. 1.

    Liquid neon is a less expensive refrigerant, on a cost per heat of vaporization basis than liquid helium, and since it is inert, it is less hazardous than liquid hydrogen,

     
  2. 2.

    Liquid neon, with 97.2 Btu/liter, has a higher heat of vaporization for an equal volume than does either liquid helium, with 2.4 Btu/liter, or liquid hydrogen, with 29.8 Btu/liter, This consideration is very important for applications having limited available space.

     
  3. 3.

    Precise temperature control can be achieved easily by varying the saturation pressure of liquid neon. In the 32°–40°K temperature range, an equilibrium pressure change of 10 psi changes the saturation temperature an average of only 0.5 °K.
