Krypton (Kr) is produced as a by-product of xenon gas manufacture. The main uses for Krypton is in the lighting industry and environmental insulation products.

The Use of Krypton Gas

In window insulation, krypton is useful as it has a low thermal conductivity and is a relatively dense gas. When used as a filler gas between two or three-ply window planes, it increases heat insulation and creates an energy-saving window by reducing solar radiation. Air Products produces krypton, xenon and rare gas mixtures to increase R-value and reduce U-factors for windows and doors to your requirements.

As a lighting gas, krypton has a blue-green light, and is traditionally used in halogen bulbs, energy saving bulbs and even neon-signs gas discharge tubes. Using krypton instead of nitrogen or argon increases the lifespan of the light bulbs greatly as krypton is highly stable and unreactive. 


Environmental Window Insulation
Air Products customises krypton mixtures for 2 or 3-ply window planes to increase R-value and reduce U-factors for windows.
Air Products customises high-purity krypton mixtures for exceptional brightness and bulb longevity.

Rare Gases

Rare gases, also known as noble gases, are the most inert and unreactive elements known to man. They are found in very low concentrations in the environment and are manufactured by Air Separation Units (ASU). Due to their unique chemical properties, experts have found very novel and interesting applications for them.

Xenon for Semiconductor and Memory Chips Manufacturing

Xenon is used for etching and deposition of microchips in semiconductor manufacturing, both as an atmosphere, plasma and as an ion beam source for etching and deposition processes. Xenon used in this process needs to be very pure as any impurities will end up contaminating the silicon substrate or reacting with the process chemicals like fluorine to produce poisonous and highly corrosive hydrogen fluoride (HF). As a global leader in servicing the electronics industry, Air Products’ xenon is produced in our state-of-the-art electronics grade plant for better quality assurance. It can be used in excimer laser, laser buffer gases, etching of DRAM and 3D NAND and plasma display panels.
