About Neon

With the name which comes from a Greek word meaning new, neon is a noble gas that has ho odor and color, non-toxic and biologically not very important. In very small amounts, neon can be found in air, especially in northern parts of the atmosphere of our planet. It is extensively used for producing so called neon lights, primarily for decorative and advertising purposes. Neon is an element that is important for producing some types of lasers, electrical indicators, equipment for sports (especially water-sports), and so on. Neon turns bright red when charged with the electric current. Liquid neon is very good refrigerant widely used for preserving low temperatures in various kinds of industries.

Uses of Neon

Neon (Ne), a chemical element and a tasteless, odorless, colorless inert gas of Group 18, is especially used for electric signs (neon signs), fluorescent lighting, high-voltage indicators, television tubes and wave meter tubes. Liquid neon is commonly used as a cryogenic refrigerant. Neon lamps (or glow lamps) are used as indicators, voltage testers, microwave and millimeter-wave detectors, and night-lights. They are also used as Nixie tubes which are electronic devices to display numerals or other info using glow discharge.

In addition, neon lighting is used by artists. There are some museums devoted to neon lighting such as the Neon Museum, the Museum of Neon Art, and the American Sign Museum. Artists who work with neon are Mary Weatherford, Glenn Ligon, Keith Sonnier, Iván Navarro, Tracey Emin, Shezad Dawood, etc.
