Air Products Argon Tech

Argon (Ar) is a monatomic, chemically inert gas which constitutes slightly less than 1% of the air. Its gaseous specific gravity is 1.38 and its boiling point is -302.6°F (-185.9°C). Argon is colourless, odourless, tasteless, non-corrosive, non-flammable, and non-toxic. Commercial argon is the product of cryogenic air separation, whereby liquefaction and distillation processes are used to produce a low-purity ‘crude’ argon product which is then purified to produce the commercial product. Argon is used primarily for its properties as an inert gas in applications such as arc welding, steel-making, heat treating, and electronics manufacturing.
