Audited Supplier Argon gas is a chemical element that belongs to the group of noble gases on the periodic table. Its atomic number is 18, and it has the symbol Ar. Argon is colorless, odorless, and tasteless, making it a non-reactive gas. It is the third-most abundant gas in the Earth's atmosphere, making up about 0.93% of the air.
Argon is obtained through the fractional distillation of liquid air. It is widely used in various applications, including:
Lighting: Argon gas is commonly used in incandescent and fluorescent bulbs to prevent the filament from oxidizing at high temperatures.
Welding: Argon is often used as a shielding gas in welding processes to protect the weld area from atmospheric contamination.
Electronics: It is used in the production of semiconductors and other electronic components to create an inert atmosphere and prevent oxidation.
Scientific research: Argon is used in laboratories for its inert properties, such as creating an oxygen-free environment for certain experiments or as a carrier gas in chromatography.
Medical applications: Argon gas is sometimes used in medical procedures, such as cryosurgery, to freeze and destroy abnormal tissues.
Preservation: It is used in the preservation of valuable artifacts and documents, as argon helps to reduce oxidation and degradation.
These are just a few examples of the many applications of argon gas. Its non-reactive nature and abundance make it a useful and versatile element in various industries.
