Formula: Xe

What Is Xenon (Xe) Gas?

Xenon (Xe) is a heavy and extremely rare noble gas. Xenon was discovered in 1898 and it was the first noble gas found to form true chemical compounds. It has a very high ionization potential, high density (more than 4.5 times heavier than air) and low heat capacity. Its atomic number is 54.

Industry Applications for Xenon Gas (Xe)

Xenon is a trace gas and is used in a wide variety of applications.

It is a component of excimer laser mixes to produce certain wavelengths. It is a required component in the gas mixes used to produce 282nm (XeBr), 308nm (XeCl), and 351nm (XeF).

Xe is used in sputter deposition, especially when depositing coatings with higher molecular weights. It is more expensive than commonly used argon, but a higher yield and better coating is obtained when coating with heavier atoms. Xenon is often used for sputter coating heavier coatings including those used to make hard disks.

Xenon has long been used as a propellant for satellites and other spacecraft. It is a preferred propellant for electric propulsion whether with Hall effect thrusters or ion thrusters. The thrusters ionize and expel the xenon at up to hundreds of kilometers per second providing in-space propulsion many times more efficient than conventional chemical propulsion. Xenon electric propulsion has been used for orbit-raising and station keeping of satellites and has been used to send space probes to Mercury and the asteroid belt.

Xenon’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 used for production of semiconductors in annealing, etching and lithography applications. Krypton acts both as surface disruption agent and a plasma modulator, influencing the composition of plasmas through secondary ionization. Historically secondary ionization and surface disruption was achieved using argon due to cost and availability, but krypton provides the ability to select for ions present in plasma in additional ways.

Xenon mixes are used in detectors including those used to detect radiation and infrared light. Xenon is even used in the very large detectors used to find dark matter.

Xenon even has some medical applications, including use to enhance MRI imaging or as anesthesia.

FAQs about Xenon (Xe)

How is Xenon (Xe) used in the aerospace industry?

The aerospace industry has been using Xenon since the 1960s. It has been used for satellite programs, space travel, and propellant for ion thrusters in spacecraft and satellites. Airports also use Xenon for runway lighting due to its bright blue hue.

Which gas is used in car headlights?

Xenon and Halogen are commonly used for car headlights. Xenon gas headlights are also more energy-efficient, using half as much energy as typical Halogen bulbs. Xenon gas has superior brightness on the road, all while minimizing the glare that shines on oncoming traffic.
