Neon

Neon: uses

The following uses for neon are gathered from a number of sources as well as from anecdotal comments. I'd be delighted to receive corrections as well as additional referenced uses (please use the feedback mechanism to add uses).

• used in making neon advertising signs, which accounts for its largest use
• used to make high-voltage indicators, lightning arrestors, wave meter tubes, and TV tubes
• neon and helium are used in making gas lasers
• liquid neon is an economical cryogenic refrigerant. It has over 40 times more refrigerating capacity per unit volume than liquid helium and more than three times that of liquid hydrogen. It is compact, inert, and less expensive than helium when it meets refrigeration requirements
