PRODUCTS / RARE GASES / KRYPTON

Description

Krypton is present in the air at about 1 ppm. The atmosphere of Mars contains a little (about 0.3 ppm) of krypton. It is characterised by its brilliant green and orange spectral lines.

Under normal conditions krypton is colourless, odourless, fairly expensive gas. Solid krypton is a white crystalline substance with a face-centered cubic structure which is common to all the "rare gases". Krypton difluoride, KrF2.

Krypton is present to a small extent (about 1 ppm by volume) in the atmosphere and is obtained as a byproduct from the liquefaction and separation of air. This would not normally be carried out in the laboratory and krypton is available commercially in cylinder.

Application

It used with argon as a low-pressure filling gas for fluorescent lights.It used in some photographic flash lamps for high-speed photography, lamps, UV-laser spectral line used for international measurement of a metre.
