Uses of Krypton Gas by Industry

Automotive & Transportation Equipment

Automotive lamp manufacturers use krypton gas to make high-quality lights for bright, long-lasting performance.

Parts Manufacturing


Krypton is a key component used in neon-based excimer laser gas mixtures, which are used to generate laser light for precise photolithography in semiconductor manufacturing.



Krypton is used in the production of specialty flat glass utilized in the solar, automotive and construction markets. Utilizing krypton in the coating process allows for glass to be manufactured with unique and specific attributes.


Window manufacturers use our krypton as an insulator in windows allowing them to meet their market needs for improving the thermal efficiency of their products.
