Krypton Molecular weight: 83.80 Melting point: -157.37℃ Boiling point: -153.35℃ Critical temperature: -63.8℃ Critical pressure: 5.5MPa Critical volume: 91.2cm³/mol Widely used in electronics industry, electric light source industry, but also used in gas lasers and other ion streams. The lamp filled with pure krypton gas has the advantages of higher luminous rate, smaller size, longer life and less electricity than the argon lamp with the same power. It is widely used in the manufacture of mining lamps, and because of its particularly high transmission rate, it can be used in the manufacture of illumination lights for cross-country combat vehicles and aircraft runway lights during night combat. Used in health care to measure cerebral blood flow. The isotope can be used as a tracer. Radioactive krypton can be used for leak detection in closed containers and continuous determination of material thickness, and can also be made into atomic lamps that do not require electricity. In addition, Kr86 is used for the international standard calibration of length, and Kr85 is used for the “kryptonation” treatment of materials. In addition, krypton gas has various applications in the aerospace field. Firstly, krypton gas is used as a propellant in space propulsion systems. Due to its stable chemical properties and good safety, krypton gas is widely used as a propellant for rockets and spacecraft. Secondly, krypton gas is used as a communication medium in space communication. Due to its low absorption rate in vacuum, krypton gas has become an ideal communication medium in space communication. Using krypton gas as a communication medium can greatly improve the efficiency and reliability of communication. In addition, krypton gas is used as a tracer in space exploration. Due to the unique atomic structure of krypton gas, its presence can be detected through spectral analysis. By adding krypton gas as a tracer to the detected substance, the properties and behavior of the detected substance can be more accurately understood. In addition, krypton gas is used as a medium for animal experiments in space biology. Exposing animals to environments filled with krypton gas can help scientists study their physiological responses and behaviors in space environments. Finally, krypton gas is also used as a regulator of aviation respiratory gases in the aviation industry. Due to its stable chemical properties and good safety, krypton gas is widely used as a regulator for aviation respiratory gases to ensure the safety of aviation personnel.
