Descrizione del gas
Krypton is a chemical element that is a colorless, odorless, and tasteless inert gas. When discharged, it turns orange red and contains trace amounts in the atmosphere. It can be separated from liquid air by distillation. The multiple spectral lines of Krypton make the ionized Krypton gas discharge tube white. The light bulb injected with Krypton gas is a very bright white light source, commonly used in the production of fluorescent lamps. Krypton, like other inert gases, has extremely inactive chemical properties and is not easily reactive with other substances. Known compounds include Krypton difluoride.
Usi principali
Widely used in the electronics industry, electric light source industry, and also in gas lasers and plasma flows. Compared with argon filled bulbs of the same power, bulbs filled with pure krypton gas have advantages such as high luminous efficiency, small size, long lifespan, and energy saving. Widely used in the production of mining lamps, due to its particularly high transmittance, it can be used to manufacture off-road combat vehicle spotlights and aircraft runway indicator lights during night combat. Used in healthcare to measure cerebral blood flow. Its isotopes can be used as tracers. Radioactive krypton can be used for leak detection of sealed containers and continuous measurement of material thickness, and can also be made into atomic lamps that do not require electricity.
