Used as a shielding gas for arc welding (cutting) stainless steel, magnesium, aluminum, and other alloys.Also used in the smelting of steel, aluminum, titanium and zirconium.Argon emits a purple glow when discharged,also used in lighting technology and filling fluorescent lamps, photocells, lighting tubes, etc.
In the process of making wine, as a filling in the beer barrel, it can replace the oxygen to prevent the raw materials in the beer barrel from being oxidized to acetic acid.
In the heat treatment process, argon is used to replace nitrogen and ammonia, and the effect is more than nitrogen and ammonia.The stainless steel is heat treated with argon gas to achieve better bending ,and it is not easy to break.
The current method of obtaining argon in the industry is to distill air.Firstly,The condenser liquefies the oxygen at a boiling point of 90.2 K. After removing the liquid oxygen,By further cooling, argon gas having a boiling point of 87.3 K can be liquefied, and finally argon gas having a boiling point of 77.35 K is left.
