Discover the industrial applications of krypton

The highly stable, non-reactive nature of krypton makes it ideal for specialized applications across several key global markets:

Electronics applications : Semiconductors and memory chips

Krypton is essential for the excimer lasers used in high-precision photolithography, continually pushing technological boundaries. Air Liquide delivers premium electronic-grade purity to satisfy strict manufacturing protocols.

Healthcare and laser surgery

In medical care, krypton powers the excimer lasers that generate ultra-precise ultraviolet (UV) light required for advanced optical procedures, including LASIK eye surgery.

Satellite propulsion for space exploration

Krypton has been successfully developed as an efficient propellant for satellite constellations requiring large volumes of gas, serving as a cost-effective alternative for space missions.

Thermal energy efficiency in insulating glass

Within the commercial glass industry, inserting krypton between double or triple glazing window panes drastically reduces thermal conductivity, enhancing indoor climate retention and lowering facility energy costs. It is also used in specialized glass coatings to improve scratch resistance and overall durability.

Advanced PVD coating processes

In Physical Vapor Deposition (PVD) vacuum sputtering processes, krypton's large atomic size optimizes magnetron sputtering. It efficiently ejects heavy molecules—such as tantalum, titanium, gold, and silver—resulting in superior, robust surface coatings.
