Frozen argon description
Argon is present in atmosphere to the extent of about 0.93%. It is colorless, odorless, tasteless and non-toxic gas. It is non-flammable and is a highly inert gas. Apply modes for argon are liquid and as compressed gas. Argon is a member of a special group of gases known as the “rare,”“noble,”or “inert”gases.
Usage
1.Used for industrial and hospital analyses quality control.
2.Protecting welds against oxidation reduction of welding emissions.
3.Used in its pure form for protection against impurities.
4.Stirring and decarburizing steel (especially stainless alloys).
5.Luminescent mixtures for filling light bulbs and fluorescent tubes
Inflating car airbags.
