General
Argon is the most abundant member in the rare gas family, which consists of other members, such as Helium, Neon, Krypton and Xenon. Argon is colourless, odourless, tasteless and non-toxic. It is slightly soluble in water.

Argon has been increasingly used in many applications, especially in metallurgical processes. It is blown into furnaces to stir the molten metal and for flushing other gases from the melt, mainly in the production of stainless steel. It is also widely used as a shielding atmosphere in welding, metal fabrication, aluminium processing, microelectronics, glass coating and advanced ceramics.

Properties
• Completely inert.
