A Guide to Argon as an Industrial Gas
Argon is a colourless, odourless and tasteless gas that makes up almost 1% of the atmosphere. It is one of the most abundant elements on Earth, second only to oxygen. Argon is also used in industries for various applications such as welding, electronics, aeronautics and more. However, purity and concentration are crucial factors in industrial processes. Since a slight variation can result in accidents, choosing the right supplier for Argon gas is crucial. Worry not because this guide covers how you can make the right choice.
How is Industrial Argon Gas made?
Argon is a noble gas. It is extracted from natural gas, a fossil fuel in the Earth’s crust. The process of extracting argon from natural gas starts with an underground well, where the argon is trapped in pockets beneath layers of rock and sediment. As this natural gas rises to the surface, it passes through pipes leading directly into processing plants, where it undergoes several steps to purify itself.
Once purified, industrial argon can be used for many purposes throughout all industries:
- Refrigeration systems use it as a coolant; it keeps food at low temperatures without freezing or melting them like water would do
- Welding uses high-powered torches which generate intense heat; using argon instead of oxygen makes steel welding easier and safer because less oxygen means less chance of fires starting during production
- Medical equipment uses small amounts while performing surgery so that patients aren’t exposed to harmful chemicals
Industrial Applications of Argon
- Semiconductor manufacturing: Argon can be used as an etching agent for silicon wafers during semiconductor fabrication processes such as photolithography or plasma etching. In addition to improving crystal structure uniformity during growth at low temperatures (below 1000°C), argon promotes low defect density when grown at high temperatures (>1000°C). This property makes it ideal for growing thick silicon layers up to 100 microns thick from molten silicon.
- Food packaging: Argon has been found useful in extending the shelf life of food items like meat or poultry products packaged under vacuum conditions because it does not support microbial growth as oxygen does, nor does it react with other components present inside these packages, which would otherwise accelerate spoilage due to oxidation reactions occurring between various types of molecules present.
Benefits of Purchasing Argon in Industries
Argon is used in many industrial applications. It is a good insulator with a low boiling point, making it ideal for refrigerant gas use. Argon gas can also make polymers, semiconductors, electronics and chemicals.
The most common use of argon is in producing polymers such as vinyl chloride monomer (VCM) and acrylonitrile butadiene styrene (ABS). For example, VCM helps produce high-quality plastic drinking water or soft drink bottles. In addition, argon helps create ABS plastics that are commonly used for making automobile parts like seats and dashboards because they are strong yet lightweight.
Semiconductors made from gallium arsenide can withstand large amounts of heat without losing their ability to conduct electricity; these semiconductors are then put into computers where they operate at very high speeds while using small amounts of power compared to other types of computer chips such as those made out of silicon dioxide materials.
Why is the Purity of Gas Crucial for Applications?
Argon purity is important for industrial applications because the gas can affect the quality of the product. If a welding application requires 99.5% argon, it must be supplied at 99.5% purity.
If you want to ensure that your argon meets industry standards and is suitable for a specific application, you need to make sure you are buying from a reliable source.

Tips for Purchasing Industrial Argon
When purchasing industrial argon, you must know what you need before buying. A reputable supplier should be able to answer your questions and offer advice on which gas would be best for your particular application. They can also provide quality certificates that will give you an idea of purity levels and any other relevant details that may be important to you.
When testing the purity of the gas, check for moisture content and toxic impurities such as hydrogen sulphide or carbon dioxide. For example, if it contains more than 100 ppm (parts per million) of CO2, this would indicate a relatively high pressure during delivery which could cause freezing damage.
