Audited Supplier Argon gas is an element that exists as a colorless, odorless, and tasteless gas at standard temperature and pressure. It is one of the noble gases, which are a group of chemically inert elements located in Group 18 of the periodic table.
Argon is the third most abundant gas in the Earth's atmosphere, making up about 0.93% of the air we breathe. It is produced through the process of fractional distillation of liquid air. Argon is also used in various industrial applications, such as in welding, where it provides an inert atmosphere to prevent oxidation during the process. It is also used in lighting, as it produces a stable glow when an electric current is passed through it, making it commonly used in fluorescent lamps and other types of lighting.
Additionally, argon is used in scientific research, as a shielding gas in certain types of laboratory equipment, and in the production of semiconductors. Its inert properties and abundance make it a versatile and valuable gas in various industries.
