Argon is an inert gas and is now widely used in the industrial sector. It is a very useful rare gas. Argon has very inactive properties. It cannot be burned and cannot support combustion, thus it has excellent stability. Argon does not undergo chemical reactions and explode; it can only explode due to the change in pressure derived from Corabellon's formula. Argon cylinders are very sturdy and will not fly apart like gas cylinders. ArF exists, but the temperature change is not significant. Generally, there are no problems even under high temperature and high pressure. 

The national standard for high-purity argon gas is GB/T10624—1995, with a quality requirement of over 99.999%.Argon gas is obtained by separating air to extract it. The liquefied air is subjected to distillation to obtain crude argon. The crude argon is extracted and further purified to obtain high-purity argon. High-purity argon is used in the semiconductor industry as a protective gas for producing high-purity silicon and germanium crystals; it can also be used as an inert gas for system cleaning, shielding, and pressurization; and it is applied in chemical vapor deposition, sputtering, and annealing processes. High-purity argon can also be used as a chromatography carrier gas. Argon is widely used to fill arc lamps, fluorescent lamps, and electron tubes; as welding shielding gas; as a shielding gas in the production of titanium, cobalt, and other active metals; and for smelting special steel in black metallurgy. 

Liquid argon is obtained by compressing high-purity argon gas into a liquid state and storing it in Dewar flasks. When liquid argon is used, it releases the gaseous phase. When stored in a Dewar flask, liquid argon undergoes a natural pressurization process. When its pressure becomes too high, the Dewar flask will perform a safety pressure relief. During this natural pressurization and pressure relief process, the argon gas is simply released.
