Argon Gas – Ar
DSW Industry is one of the premier argon gas suppliers, producing liquid and gaseous forms to suit various applications.
What is Argon?
Argon is the first noble gas to be discovered. It was identified by the English physicist Lord Rayleigh and Scottish chemist William Ramsay in 1894. Argon is from the Greek word “Argos,” which means “lazy” or “inactive.” It belongs to noble gas and is about 0.93% of Earth’s atmosphere. It is the third most abundant gas in the atmosphere. Non-flammable cryogenics gases are sometimes referred to as inert gases.

Chemical Properties of Argon-Ar
Argon is a noble gas that is chemically inert. Still, at low temperatures, it is possible to combine with other atoms to form very fragile compounds at very low temperatures. Since this element does not exhibit any chemical reactivity, it is called a noble gas.
Uses of Argon–Ar
- Argon-enhanced electrosurgery uses argon gas to increase the effectiveness of the ESU, resulting in less tissue damage and less blood loss.
- Argon plasma coagulation uses electricity-conductive argon plasma as a medium to deliver a high-frequency current to coagulate tissue. The non-contact feature permits rapid coagulation with minimal manipulation and trauma to the target tissue.
- In the electric lamp industry, argon is the standard filling for incandescent filament lamps, and neon discharge tubes are familiar in advertising signs.
Frequently Asked Questions
What are the uses of argon gas?
Argon gas is widely used to fill up incandescent and fluorescent light bulbs to prevent oxygen from corroding the bulb’s filament (usually heated to very high temperatures). Argon also forms inert atmospheres that require shielding from other atmospheric gases for arc welding, rising semiconductor crystals, and other processes.
How is argon produced?
Industrially, argon gas is produced via the fractional distillation of liquid air in a cryogenic air separation unit; This procedure separates liquid nitrogen (boiling point: 77.3 K) from argon (boiling point: 87.3 K) and liquid oxygen (boiling point: 90.2 K). Every year about 700,000 tons of argon is produced around the world.
Is argon gas toxic?
Even though argon gas is non-toxic, in closed areas, it is 38 percent denser than air, and it, therefore, can be considered a dangerous asphyxiant. It’s hard to spot because it’s colorless, odorless, and without taste.
