Commercial Production of Liquid Neon
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,
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.
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.
