Neon is a very common element in the universe but is fairly rare on the Earth. This post will take you through some of the common uses of neon. It is important to remember that neon is not used for many things as it is very expensive. It can be more than 50 times the cost of helium as it is much rarer.
Uses of Neon
- Neon is often used in advertising signs. It produces a bright reddish-orange color. Some other lights with different colors are sometimes called neon lights. However, these are produced with other noble gases.
- The triple point of neon (the temperature where liquid, gas and solid neon all exist at the same time) is a defining fixed point in the International Temperature Scale of 1990.
- Liquid neon is often used as a cryogenic refrigerant where the extremely low temperatures requiring liquid helium are not needed. It is more effective than helium so, despite the higher cost, may be more viable.
- Neon is also used in vacuum tubes, high-voltage indicators, lightning arresters (which protect electrical equipment from lightning strikes), wave meter tubes, television tubes and helium-neon lasers.
