Argon (Greek argos meaning "lazy")
terrestrially the most abundant and industrially the most frequently
used of the noble gases. Argon is used in the fanciest, most energy-efficient
double-pane insulated windowsis, in gas-filled electric light
bulbs, radio tubes, and Geiger counters. It also is widely utilized
as an inert atmosphere for arc-welding metals, such as aluminum
and stainless steel; for the production and fabrication of metals,
such as titanium, zirconium, and uranium; and for growing crystals
of semiconductors, such as silicon and germanium.
