Argon is now more and more widely used in industrial and chemical processes, so what are the characteristics of such a gas? Let's take a look.

Argon is a colorless, odorless, odorless, non-toxic, monatomic noble gas whose density is 1.4 times that of air and 10 times that of helium. Argon can not burn or support combustion. It does not react chemically with other substances at room temperature. Its chemical properties are very inactive and its stability is very good. It is also insoluble in liquid metal at high temperature, and it can show its superiority when welding non-ferrous metals. Therefore, argon is currently widely used in the industrial welding industry. It is a very important inert rare gas in industrial welding production. It is used as a welding shielding gas to prevent the welding parts from being oxidized or nitrided by air.

Argon gas can be stored and transported in liquid form at temperatures below -184°C, but argon gas for welding is mostly used in steel cylinders.

Collision and knocking are strictly prohibited during transportation and use.

It is necessary to protect the bottle valve. When the bottle valve is frozen, do not bake it with fire.

After use, the gas in the bottle cannot be used up completely, and the pressure of not less than 0.2MPa needs to be stored.

When stored, it needs to be stored upright and protected from sunlight.

The production of argon can use air separation to extract argon, and use the liquefied air for rectification to obtain crude argon. After further purification, high-purity argon can be obtained. High-purity argon is used in the semiconductor industry to produce high-purity silicon and germanium. Shielding gas for crystals; can be used as an inert gas for system cleaning, shielding and pressurization; has applications in chemical vapor deposition, sputtering, and annealing processes.
