Neon is used in gas-discharge tubes, high-voltage indicators, wave meter tubes, warning lights, lightning arrestors, radio devices, television tubes as well as in cryogenic technology. Neon and helium mixture is used in helium-neon lasers. The reddish-orange color that neon emits in neon lights is widely used to make advertising signs and is used in long tubular strips in car modification.
Liquefied neon is commercially used as a cryogenic refrigerant in applications not requiring the lower temperature range attainable with more expensive liquid helium refrigeration. Recently it was also used as a neutral atmosphere, but then neon was replaced by less expensive argon. |
