Ar-Liquid Argon
A colorless, odorless, nonflammable cryogenic liquid
Liquid argon is produced in large quantities at air separation plants which liquefy and distil air into oxygen, nitrogen, and argon
Liquid argon is tasteless, colorless, odorless, noncorrosive, nonflammable, and extremely cold. Belonging to the family of rare gases, argon is the most plentiful, making up approximately 1% of the earth’s atmosphere. It is monatomic and extremely inert, forming no known chemical compounds.
Although used more commonly in the gaseous state, argon is commonly stored and transported as a liquid, affording a more cost-effective way of providing product supply.
Liquid Argon at -302°F is clear and odorless. Ludonggas supply Liquid Argon to commercial customers in South East Asian countries, South Asia, Africa and South Ameican countries by T75 ISO tanks.
Application and Use
|
Electronics |
In the semiconductor industry, argon is used in a number of device fabrication steps but its largest volume use is as a protective atmosphere in the manufacture of single-crystal silicon by a number of processes known as crystal pulling. |
|
Fabrication |
Argon is used as a shielding gas for MIG and TIG Welding processes and plasma-cutting. Argon is used alone or mixed with other gases such as helium, carbon dioxide, oxygen, nitrogen or hydrogen. |
|
Lasers |
Argon can be used as the assist gas for the laser cutting of titanium as well as laser welding in CO2, ND: YAG and diode machines. |
|
Metals |
The argon-oxygen decarburising (AOD) process is the most common method of refining stainless steel. Argon is used to prevent oxidation of molten metals and alloys and for degassing and desulphurisation of molten iron and steel. |
|
Spectrographic analysis |
Arc-spark analysis uses argon in the process of measuring the characteristic wavelength of light generated by striking an arc onto the metallic sample being analysed. |
|
Window unit insulation/Double-glazing |
Argon is used to fill the inter-space in double-glazed window units because of its low thermal conductivity relative to air or nitrogen. |
