Argon A colorless, odorless, nonreactive, inert gas which is compressed to high pressures. It acts as a simple asphyxiant by displacing air. Argon belongs to the family of inert rare gases of the atmosphere. It is extremely inert and forms no known chemical compounds.
Argon is recovered from plants producing oxygen and nitrogen.
These plants liquefy air which goes under a distillation process to remove oxygen, nitrogen, argon, and some of the other rare gases. Gaseous argon is commonly stored in high pressure cylinders, tubes, or tube trailers. Liquid argon is commonly stored at the consumer site in cryogenic liquid cylinders and specially designed vacuum insulated storage vessels.
