Gaseous Argon

Gaseous argon is tasteless, colorless, odorless, noncorrosive, and nonflammable. Argon belongs to the family of rare inert gases. It is the most plentiful of the rare gases making up approximately 1% of the earth’s atmosphere. It is monatomic and extremely inert, forming no known chemical compounds. Since argon is inert, special materials of construction are not normally required. Vessels and piping must be selected and designed to withstand the pressure and temperatures involved and comply with applicable codes and regulations.



Argon is produced by an air separation unit (ASU) through the liquefaction of atmospheric air and separation of the argon by continuous cryogenic distillation. The argon is then removed as a cryogenic liquid.



Argon serves as a shielding gas to protect metals from oxidation during welding. Inert gas welding is the preferred method of joining several ferrous and nonferrous alloys. The metals and semiconductor manufacturing industries employ argon as a purge or inerting gas in furnaces or other processing steps. In some instances, liquid argon is introduced and then vaporized over the surface of volatile or reactive molten metals to significantly reduce oxidation and/or volatility using an inert “blanket” of gas. High-volume flow rates of argon are introduced via specialized lances or “tuyeres” in a variety of melting and refining processes. The argon typically acts as a “shroud” gas to provide protection to the tuyere. It also promotes the removal of impurities and/or dissolved gases in several refining processes. Argon is also widely used in the lighting industry for filling bulbs and in combination with other rare gases for special color effects.

Thermal Spraying

Argon is a key process gas for many thermal spray applications, particularly plasma spraying. Since argon is completely inert and easily ionized, it can be used as the primary plasma gas or as a secondary gas with nitrogen to increase its energy. It can also be used as a powder carrier gas for a completely inert environment. Our application engineers can help you select a supply system to meet your pressure and volume requirements.
