Argon is an inert gas, now widely used in industry, is a kind of very useful gases, argon gas nature very vivid, it can not burn, nor combustion-supporting, thus the stability is very good, argon gas won't react and explosion, is only possible because cora veron equation deduced the pressure change and explosion. Argon canisters are strong, and they don't fly in single sheets like gas canisters. ArF does exist, but the temperature does not change much.

The national performance standard of high purity argon is GB/ T10644-1995, and the quality requirement reaches over 99.999%.

Argon is extracted by air separation, in which the liquefied air is rectified to obtain the crude argon. The crude argon is extracted and further purified to obtain the high-purity argon, which is used as a protective gas to produce high-purity silicon and germanium crystals in the semiconductor industry. An inert gas that can be used for system cleaning, shielding and pressurization; It has been used in chemical gas phase stacking, sputtering and annealing. High purity argon is also used as a chromatographic carrier gas. Welding protective gas; Used as shielding gas in the production of titanium, cobalt and other active metals; Used for blowing special steels in ferrous metallurgy.

Liquid argon is made by compressing high-purity argon into liquid gas and storing it in a dewar tank. When the liquid argon is used, the gas phase is released. When the liquid argon is stored in the duar tank, it will undergo a natural pressurization process. When the pressure is too high, the duar tank will perform a safe pressure relief.
