Product Description

Argon is the third most common gas in the Earth's atmosphere, at 0.93% .argon is the most prevalent of the noble gases in Earth's crust. Argon is produced industrially by the fractional distillation of liquid air. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial 

processes where ordinarily non-reactive substances become reactive; for example, an argon 

atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Argon gas also has uses in incandescent and fluorescent lighting, and other types of gas discharge tubes. Argon makes a distinctive blue-green gas laser. Argon is also used in fluorescent glow starters.

Safety protection of cryogenic liquid argon 

Argon itself is nontoxic, but suffocates at high concentrations. When the air concentration is higher than 33%, that is, when oxygen concentration is reduced by 2/3 or less than usual, there is a danger of asphyxiation. %, Serious symptoms, concentrations of 75% or more, can die within a few minutes.

Asphyxia symptoms include initial resuscitation, loss of attention, imbalanced muscle activity, subsequent loss of judgment, loss of feeling, emotional instability, generalized tiredness, nausea, vomiting, weakness, loss of consciousness, recovery, lethargy , Resulting in death. Liquid argon splash into the eyes can cause inflammation, touching the skin can cause frostbite. Argon can be stored in glass bottles or cylinders.

Argon gas uses have many special uses
Argon can be used for welding, stainless steel manufacturing, smelting, also used in chemical vapor deposition, crystal growth, thermal oxidation, epitaxy, diffusion, polysilicon, tungsten, ion implantation, current carrying, sintering and other argon in semiconductor manufacturing process As a protective gas for producing single crystals and polysilicon, in order to improve the quality of silicon crystals, how to use higher purity argon gas is an issue for fabricating silicon crystals. Through the use of this device, the purity of argon, wherein the oxygen content is less than 1ppm, the moisture content is less than 1ppm, the monocrystalline silicon produced has an oxygen carbon content of less than 0.5ppm, which improves the service life of the single crystal and can be achieved Requirements, to win customer satisfaction and market demand. Since the general liquid argon vaporizes without purification, its oxygen content is generally in the range of 2 ppm to 5 ppm. Sometimes the argon supplied by gas suppliers exceeds this range, but customers using argon do not know their quality, so they often have an impact on the quality of production products. With the argon purification device, regardless of the quality of the argon feed gas, the purity of the argon gas in the crystal pulling furnace is always constant as long as it is treated by the purification device. Generally O2<0.2ppm, moisture<1ppm, so stable argon gas is guaranteed to produce crystal quality.
