Odorless High Purity Gases Welding Argon Gas Non Toxic UN No. UN1006
Argon has approximately the same solubility in water as oxygen, and is 2.5 times more soluble in water than nitrogen. Argon is colorless, odorless, nonflammable and nontoxic as a solid, liquid, and gas. Argon is chemically inert under most conditions and forms no confirmed stable compounds at room temperature.
Although argon is a noble gas, it can form some compounds.
Argon fluorohydride, a compound of argon with fluorine and hydrogen that is stable below 17 K, has been demonstrated. Although the neutral ground-state chemical compounds of argon are presently limited to HArF, argon can form clathrates with water when atoms of argon are trapped in a lattice of water molecules. Ions, such as ArH+, and excited state complexes, such as ArF, have been demonstrated. Theoretical calculation predicts several more argon compounds that should be stable but have not yet been synthesized.
The main isotopes of argon found on Earth are 40Ar , 36Ar, and 38Ar.
Argon's complete octet of electrons indicates full s and p subshells. This full outer energy level makes argon very stable and extremely resistant to bonding with other elements.
Argon is produced industrially by the fractional distillation of liquid air in a cryogenic air separation unit; a process that separatesliquid nitrogen, which boils at 77.3 K, from argon, which boils at 87.3 K, and liquid oxygen, which boils at 90.2 K. About 700,000 tonnes of argon are produced worldwide every year.
Argon has several desirable properties:
Argon is chemically inert gas.
Argon is the cheapest alternative when nitrogen is not sufficiently inert.
Argon has low thermal conductivity.
Argon has electronic properties desirable for some applications.

|High purity argon gas
|Hazardous class for transort
2. Typical technical data (COA)

|According to the valve type
|Other sizes and other standards are also available
|An argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Argon is used in various types of arc welding such as gas metal arc welding and gas tungsten arc welding, as well as in the processing of titanium and other reactive elements. An argon atmosphere is also used for growing crystals of silicon and germanium.
|Liquid argon is used as the target for neutrino experiments and direct dark matter searches
|Argon is used to displace oxygen- and moisture-containing air in packaging material to extend the shelf-lives of the contents
|Argon may be used as the carrier gas in gas chromatography and in electrospray ionization mass spectrometry; it is the gas of choice for the plasma used in ICP spectroscopy.
|In surgery it is used in a procedure called "argon enhanced coagulation" which is a form of argon plasma beam electrosurgery.
|Incandescent lights are filled with argon, to preserve the filaments at high temperature from oxidation. It is used for the specific way it ionizes and emits light, such as in plasma globes and calorimetry in experimental particle physics. Gas-discharge lamps filled with pure argon provide lilac/violet light, filled with argon and some mercury blue light. Argon is also used for the creation of blue and green laser light.
