Krypton, Kr Specialty Gas

What is Krypton Gas?

Krypton (Kr) is a rare gas of Group 18 (noble gases) of the periodic table, which forms relatively few chemical compounds. Kr gas is a colorless, odorless, tasteless gas that occurs in trace amounts in the atmosphere.

Krypton Gas Industry Applications

A noble gas, Krypton is used in a wide variety of applications. These applications take advantage of krypton’s low ionization and high atomic mass.

Much krypton is used for window insulation. It insulates better than argon or air when put between the panes of double or triple-pane windows. Krypton provides for lower U-factors (higher R-values) with the same window design. Additionally, krypton offers additional benefits with thin spacings between panes making more high-performance designs possible.

Krypton’s physical and chemical properties make it useful in lighting applications. It is used in incandescent, halogen, fluorescent, and high-intensity discharge lamps.

It is a component of excimer laser mixes to produce specific wavelengths. It is a required component in the gas mixes used to produce 222nm (KrCl) and 248nm (KrF) UV.

Krypton is used in sputter deposition, which is a type of physical vapor deposition. It offers advantages when depositing coatings with higher molecular weights. Krypton is more expensive than commonly used argon but provides a higher yield, and better coating is obtained when coating with heavier atoms. Krypton is often used for sputter coating heavier coatings like titanium.

Krypton Safety Requirements:

The cryogenic liquid will rapidly boil into a gas at standard temperatures and pressures. The liquefied gas can cause frostbite and contaminate any tissue in proximity. The primary health hazard of releasing this gas is asphyxiation by oxygen displacement (see SDS for further information).
