What is argon used for?

Answer 1

Argon is used in applications where an inert atmosphere is desirable (for example, it's sometimes used to keep materials from catching on fire at high temperatures). It's occasionally used in "neon" lights where it produces a bluish light, is often used as a carrier in gas chromatography, and is the usual gas used to create the plasma in inductively coupled plasma spectroscopy.

Argon can be used to make lightbulbs, glow tubes, photo tubes, and fluorescent tubes. To grow silcon crystals. Vacuum tubes.
Argon, which has the chemical symbol Ar, is the third most common gas in the Earth's atmosphere after nitrogen and oxygen. Here are some of the more common uses of argon in the world today!

Uses of Argon

• Argon gas is used in graphite electric burners to prevent the graphite from burning. The graphite would burn in normal air with oxygen present.
• Crystals of silicon and germanium are grown in the presence of argon.
• Argon is used to kill pigs humanely if there is an outbreak of some disease on the farm.
• Occasionally, argon is used to put out fires when it is vital that equipment is not damaged.
• Argon, in liquid form, is used by scientists to look for dark matter.
• Argon can be used to preserve paint, varnish and similar things for storage after opening.
• The American National Archives use argon to store important national documents (like the Declaration of Independence). This prevents the documents being destroyed by the air.
• In the science laboratory, argon is often used as a carrier gas in gas chromatography.
• While there are some risks, liquefied argon can be used to kill cancer cells in a procedure called 'argon enhanced coagulation'.
• Blue argon lasers are used in surgery to weld arteries and correct eye problems.
• Speaking of blue, blue laser lights are made with argon.
• Lights are filled with argon to prevent the filament from reacting with air.
• Scuba divers use argon to inflate a dry suit.

Answer 2

Argon is used in incandescent light bulbs to keep the filament from oxidizing. It is used in fluorescent "neon" lights (many of which don't actually contain neon). It is also used in containers for highly reactive substances such as the highly reactive alkali metals because it will not react with them.

Answer 3

Argon gas is commonly used in industrial applications such as welding, metal production, and electronics manufacturing. It is also used in lighting, such as in fluorescent bulbs and Photography. Additionally, argon is utilized in analytical chemistry and scientific research.
