Krypton is concentrated in the atmosphere, occupying 1.1ppm in the atmosphere. Krypton is chemically inert under all normal conditions

Krypton (Kr), a noble gas in group 18 (noble gases) of the periodic table, forms relatively few compounds. Krypton is a colorless, odorless, and tasteless gas that exists in trace amounts in the atmosphere.


Krypton industry application

Krypton is an inert gas with many uses. These applications take advantage of krypton's low ionization and high atomic mass.

A lot of krypton gas is used to insulate windows. When placed between the panes of double or triple glazed windows, it insulates better than argon or air. Krypton offers a lower U-factor (higher R-value) with the same window design. In addition, Krypton offers the added benefit that the spacing between panels is small, enabling more high-performance designs.

Krypton's physical and chemical properties make it useful for lighting applications. It is used in incandescent, halogen, fluorescent and high-intensity discharge lamps.


Main uses of krypton

Lighting: Krypton is used in some types of light bulbs, especially in flashlights and some types of fluorescent lamps. In these applications, krypton is able to produce specific colors and brightness, which are suitable for occasions such as photography and stage lighting.

Laser technology: Krypton is one of the key ingredients in the manufacture of several types of lasers, especially krypton ion lasers and krypton fluoride (KrF) excimer lasers. Krypton ion lasers are able to produce visible light from green to red, while KrF excimer lasers are mainly used in the ultraviolet region with a wavelength of about 248 nanometers and are widely used in photolithography during the semiconductor manufacturing process.

Scientific research: Due to its physical and chemical properties, krypton is also used as an important tool in scientific research, especially in the fields of low temperature physics, nuclear physics and astrophysics.

Other applications: Krypton is also used as a filling gas in double-glazed windows to improve thermal insulation; and in some types of thermocouples to measure high temperatures.
