| Xenon
is a
"rare" gas, since it only account for one
thousandth of the air which surround us. It is so inert that they do
not react and can only be combined with other chemical substances
with great difficulty. Its extreme inertness makes them very
valuable for certain applications. |
| Used
in incandescent lamps (automobiles and aviation), photographic flash
bulbs, flat television screens (plasma display), in "excimer"
lasers, xenon can produce wavelengths which vary as a function of
operating conditions. It can be used light sources which operate in the
ultraviolet range., Xenon is also used in high energy particle physics
research. Being dense and easily ionized and having a high propulsive
capacity, xenon is the ideal gas for positioning satellites. By this way,
xenon gradually replaces chemical propellants for satellite-positioning
ion motors. |
