Industrial High Purity Argon Gas For Welding , Colourless Flammable Gas
Description:
Argon is a chemical element with symbol Ar and atomic number 18. It is in group 18 of theperiodic table and is a noble gas. Argon is the third most abundant noble gas 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 unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Argon is also used inincandescent, fluorescent lighting, and other gas discharge tubes. Argon makes a distinctiveblue-green gas laser. Argon is also used in fluorescent glow starters.
Argon constitutes 0.934% by volume and 1.288% by mass of the Earth's atmosphere, and air is the primary industrial source of purified argon products. Argon is isolated from air by fractionation, most commonly by cryogenic fractional distillation, a process that also produces purified nitrogen, oxygen, neon, krypton and xenon. The Earth's crust and seawater contain 1.2 ppm and 0.45 ppm of argon, respectively.

Applications:
Industrial processes | 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. |
Scientific research | Liquid argon is used as the target for neutrino experiments and direct dark matter searches |
Preservative | Argon is used to displace oxygen- and moisture-containing air in packaging material to extend the shelf-lives of the contents |
Laboratory equipment | 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. |
Medical use | In surgery it is used in a procedure called "argon enhanced coagulation" which is a form of argon plasma beam electrosurgery. |
Lighting | 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. |
