Argon is a rare atmospheric gas which is colorless, odorless, tasteless, and nontoxic. It is considered extremely inert and forms no known chemical compounds. The concentration of argon gas in the atmosphere by volume is 0.93%. Argon gas has numerous applications, including neon signs, lasers, incandescent and fluorescent lamps, electronic tubes, window insulation, welding, and semiconductor applications. Numerous purities of argon gas are available for specific industrial purposes.

Argon is used because of its inert properties for protection against the oxidizing effect of air. Argon is widely used as a blanketing or shielding gas in metallurgy and arc welding and cutting. Argon is also used to fill incandescent and fluorescent lamps and windows.

Argon is a colorless, odorless, tasteless and nontoxic gas. Argon, along with helium, neon, krypton, xenon and radon is also known as a "rare" gas. Argon forms no known chemical compounds. The gas is 1.38 times heavier than air and is slightly soluble in water. Argon is present in the atmosphere at a concentration of 0.93%. Argon is recovered from air in an Air Separation Unit (ASU) where it is drawn off as a cryogenic liquid at about -303°F. Argon can then be distributed as a cryogenic liquid or as a gas in cylinders.
