What are the hazards of argon?
Dangers of Argon That argon is chemically inert does not, unfortunately, mean that it is free of potential health hazards. Argon gas can irritate the skin and the eyes on contact, and in its liquid form it can cause frostbite (there are relatively few uses of argon oil, and "argan oil," a common ingredient in cosmetics, is not even remotely the ...
What are the uses of argon in everyday life?
Argon is used in incandescent light bulbs to prevent quick oxidation of the filament. This prolongs the life of the bulb. Food and Drink Industry. Due to its inertness, argon can be found within the food and drink industry. Within drinks, argon is added to wine barrels to displace air. Being denser than air, it settles above the liquid ...
How much does antimony cost per gram?
per gram Min Order: 5 grams Supply ability: 100kg per month Antimony trioxide is primarily used as a plastic catalyst in the manufacture of polyethylene terephthalate (PET) plastic. $ 2,900.00 $ 2,100.00
Is argon gas safe?
Pro: Argon Gas is Safe If the idea of gas makes you nervous, you’ll be pleased to know that argon is completely safe. Argon is inert, meaning it’s chemically inactive. You may remember it from chemistry class as one of the noble gases, ones that are stable and don’t bond with anything else to form compounds.

What temperature does argon melt?
Melting Point (MP), Argon changes its state from solid to liquid at -189.37°C ( -308.866°F or 83.78K)
What is a compound price calculator?
The compounds and materials price calculator performs conversions between prices for different weights and volumes. Selecting a unit of weight or volume from a single drop-down list, allows to indicate a price per entered quantity of the selected unit.
What is Argon?from airgas.com
Argon (Ar) is an inert colorless, odorless, tasteless, non-corrosive, non-flammable and non-toxic gas.
What percentage of the atmosphere is argon?from britannica.com
Argon constitutes 1.288 percent of the atmosphere by weight and 0.934 percent by volume and is found occluded in rocks. Although the stable isotopes argon-36 and argon-38 make up all but a trace of this element in the universe, the third stable isotope, argon-40, makes up 99.60 percent of the argon found on Earth.
How is argon produced?from britannica.com
A major portion of terrestrial argon has been produced, since the Earth’s formation, in potassium -containing minerals by decay of the rare, naturally radioactive isotope potassium-40. The gas slowly leaks into the atmosphere from the rocks in which it is still being formed.
What temperature does argon gas condense?from britannica.com
Argon gas condenses to a colourless liquid at −185.8 °C (−302.4 °F) and to a crystalline solid at −189.4 °C (−308.9 °F). The gas cannot be liquefied by pressure above a temperature of −122.3 °C (−188.1 °F), and at this point a pressure of at least 48 atmospheres is required to make it liquefy.
Do argon atoms combine?from britannica.com
Argon atoms do not combine with one another; nor have they been observed to combine chemically with atoms of any other element. Argon atoms have been trapped mechanically in cagelike cavities among molecules of other substances, as in crystals of ice or the organic compound hydroquinone (called argon clathrates).
How abundant is argon?from en.wikipedia.org
Argon is the third-most abundant gas in the Earth's atmosphere, at 0.934% (9340 ppmv ). It is more than twice as abundant as water vapor (which averages about 4000 ppmv, but varies greatly), 23 times as abundant as carbon dioxide (400 ppmv), and more than 500 times as abundant as neon (18 ppmv). Argon is the most abundant noble gas in Earth's ...
How much argon is in the atmosphere?from en.wikipedia.org
Argon constitutes 0.934% by volume and 1.288% by mass of the Earth's atmosphere. 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.

What is the gas of choice for plasma?from en.wikipedia.org
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. Argon is preferred for the sputter coating of specimens for scanning electron microscopy.
What is the purpose of argon in packaging?from en.wikipedia.org
Argon is used to displace oxygen- and moisture-containing air in packaging material to extend the shelf-lives of the contents (argon has the European food additive code E938) . Aerial oxidation, hydrolysis, and other chemical reactions that degrade the products are retarded or prevented entirely. High-purity chemicals and pharmaceuticals are sometimes packed and sealed in argon.
