  • Applications

    Xenon (CAS 7440-63-3) is widely used as an inert shielding and processing gas in metalworking and welding, maintaining a non-reactive environment and reducing contamination for processes such as annealing and coating. In lighting and projection, xenon arc and HID lamps provide high-intensity illumination for cinema, signage, and automotive headlamps. In aerospace, xenon serves as the propellant in electric propulsion systems (ion thrusters) for spacecraft. In photonics and laser processing, xenon-based excimer lasers (e.g., XeCl, XeF) and xenon lamps are used for UV curing and surface treatment in microfabrication. In electronics manufacturing, xenon can be used as a process gas in plasma etching and deposition steps. In scientific research and analytics, xenon may be used as a reference or carrier gas for certain analytical instruments and plasma studies.
