A noble gas called argon is part of the inert gases family. A colourless and odourless gas, an inert gas has neither a visible nor a detectable odour. Argon is named after the Greek word for “lazy” because of its limited reactivity and inability to create numerous compounds. Atomic number 18 designates this gas, the third most prevalent in the atmosphere and the most abundant in the crust. Its chemical symbol is Ar. An abundance of radioactive isotope 40 has been found in the atmosphere, whereas argon-36 is the most prevalent element in space. Because it inhibits the oxidation of weld metals, argon gas creates an inert environment that is often used in welding. Argon is used in a broad range of industries for several applications.
A large part of the healthcare industry
Argon is commonly used in the medical industry, which you may not have realised. Other applications for argon lasers, also used to treat retinal separation, include welding arteries and eliminating tumours. The argon laser system’s principal usage is in the medical business, where it can precisely target specific areas. Cryo-needles are frozen in argon cryosurgery as part of the treatment procedure for kidney tumours. Healthy tissue may be removed with the use of frozen needles. Argon is also used to treat cardiac arrhythmias, abnormalities in the heart’s rhythm.
Uses for Lighting
Filling the neon tubes with argon is standard practice in the lighting industry. When exposed to electricity, argon emits a purple-blue light—the lower the voltage, the lesser the light output. The cheaper cost of this gas quickly made it a popular choice for this application. Fluorescent lighting also has a similar effect on the human eye. Incandescent light bulbs that employ argon slow filament oxidation. As a result, the lifetime of the light bulb is increased.
When it comes to the food and drink industry,
Because of its inertness, argon may be found in the food and beverage industry. There is no air in wine barrels. Thus they are filled with argon. Because of its significant density, the wine is shielded against oxidation and degradation. This restriction also applies to open bottles of wine and other liquids in bars and restaurants.
Argon is often used when welding or casting titanium or other speciality alloys. Arc welding also uses shield gas, which protects the metal from oxygen. It is possible to employ either pure argon or argon mixtures in TIG, an acronym for inert tungsten gas. In the steelmaking process, argon reduces the loss of chromium, enabling the required carbon content to be met at lower and lower temperatures. Argon is also used to remove hydrogen and degas aluminium during the manufacturing process.
Historic records should be preserved.
The preservation of historical documents is another notable use of argon. Because of its inertness, argon gas may create a safe atmosphere. Because of this, they won’t be destroyed when in storage or display.
Luminaires, ventilators, and home appliances
Argon may be used for various household tasks that you may not have previously considered. Argon is used as a thermal insulator between the panes in energy-efficient windows. To see whether your windows are loaded with toxic gas, look for two small holes in the spacer material. Using one of these holes, argon is pumped in while air is expelled.
Taking a dip in the ocean
In cold-water diving, an argon drysuit protector may be used to keep you warm and dry. Argon’s inertness and poor heat conductivity make them useful here. Argox, a colloquial word for the combination of argon and oxygen used in scuba diving breathing gas, may also be used. It’s also worth noting that this is an infrequent use scenario.
Due to argon’s cheap cost and availability, argon is often used in many industries. This gas, which makes up around one per cent of the atmosphere, may be produced by combining liquid oxygen with liquid nitrogen.
