BRIEF DESCRIPTION
Krypton is a colorless, odorless and tasteless inert gas . Krypton shows a yellow-green glow when it is discharged . It contains trace amounts in the atmosphere and can be separated from liquid air through fractionation. Krypton-infused light bulbs are very bright light sources and are often used to make fluorescent lamps. Krypton, like other inert gases, is extremely inactive chemically and does not easily interact chemically with other substances.

Chemical properties (CHEMICAL PRO)
Krypton is a rare gas. Krypton is concentrated in the atmosphere and accounts for 1.1ppm in the atmosphere. Mainly used in halogen lamps, rice lamps, high-efficiency fluorescent lamps, counting tubes, laser light sources, ultraviolet sources, standard gases, special mixed gases, etc. Krypton has a larger molecular weight and lower thermal conductivity than argon , making it an excellent filling gas . Lamps filled with krypton gas include: incandescent lamps, fluorescent lamps, flash arc lamps, iodine lamps, etc. Krypton lamps save 20% to 25% electricity than argon lamps of the same power , and have a lifespan 2 to 3 times longer. On airport runways, krypton- filled flash arc lamps are usually used for lighting because of their ability to penetrate fog. Krypton gas can absorb X-rays and can be used as a light-shielding material when X-rays are working. Can be used to make atomic lamps that do not require electrical energy. Krypton gas lamps have a particularly high transmittance and can therefore be used for lighting on off-road vehicles during night battles.
Precautions for Krypton Gas : Krypton gas is a colorless, odorless, non-toxic, non-flammable, high-pressure gas stored in cylinders. When the krypton content increases and the oxygen content falls below 19.5%, it may cause asphyxia.
