• Application of argon gas in heat treatment: Argon gas is an ideal protection environment for metals that easily react with nitrogen gas, or need protection from nitrogen gas.
  • It is used for refining metals
  • The argon gas is used pumping drysuit in scuba diving.

  • Argon gas is an inert gas and a poorer conductor of heat than conventional air, so that it is suitable material to produce high quality heat conductor when placed between small glass panels.

  • Argon gas is indispensable for laboratories in universities, the centers of laboratory analysis, research institutes or petrochemical technology, …

  • In inerting and cleaning: Argon gas is used for tanks and pipes designed in factories specializing in pharmaceuticals and chemicals.

  • In producing semiconductors, it is used as a protective coating that allows the cultivation of crystals of silicon and germanium.
  • In addition, a novel application of Argon gas is to pump car tires.
  • In welding: Argon gas is used to protect molten metals from environmental contamination in either pure or mixed form.
  • In Cutting: We need to mention an outstanding application of Argon gas which is plasma cutting of black and non-black boxes. In this application, high purity Argon is used at extremely high temperature.


MIGCO Industrial Gas Company is a wholesale as well as retail supplier of Argon gas, industrial gases and other pure gases in Ho Chi Minh City and all nationwide provinces.

What is Argon gas?

Argon (Ar) is the most common rare gas on Earth, accounting for 1% of the atmosphere and 1.3% of the mass of the planet. Argon is a colorless, odorless, tasteless and non-toxic gas. The density is 1.5 times heavier than air.

argon is a rare and inert gas, so it does not react with other chemicals. Currently Argon is produced and classified according to purity. Purity levels are divided into 2 types, the common one is 99,999% or less and the another one is purer, 99,999% or more.

Argon gas is stored and transported in the gas state in a steel cylinders, or using a car tank at pressure of 15 MPa or 20 MPa at 20 degrees C.

Neither solid Argon nor liquid Argon react chemically with other substances and dissolve the metal. But its solubility in water is close to Oxygen’s.

The atomic symbol of argon is: Ar. The main isotopes of argon currently found on Earth are Ar40, Ar 36 and Ar 38.


  • Argon gas is extremely inert, colorless and odorless in both gaseous and liquid forms. It will not make real chemical compounds.
  • Argon is 2.5 times more soluble in water than nitrogen, it means the solubility of Argon in water is on par with oxygen.
  • Natural argon is a mixture that contains all three of the isotopes, and scientists have identified 12 other radioactive isotopes of argon.


In 1785, Henry Cavendish was the first to suspect the presence of a new gas in the air or in the atmosphere, but that was only a personal statement. Argon was not recognized as a defined gas until Rayleigh’s third baron – Lord Rayleigh and William Ramsay discovered it by separating it from liquid air in 1894.

Argon was discovered thanks to the attempts of scientists to find a way to explain why the density of N extracted from the air differed from the one from the decomposition of ammonia.

William Ramsay removed all the nitrogen gases he had extracted from the air by reacting them with hot Magie. The product of this reaction was solid magnesium nitrate.

Then, there is a residual inert gas that has no reaction. And when he checked the gas’s spectrum, he found new red and green groups and a new element was confirm since then.

Argon-37 is usually produced from the decay of calcium-40 or the result of above-ground nuclear explosions. It has a half-life of about 35 days.

The argon gas will be generated by fractionated liquid air distillation because Argon makes up 0.934% of Earth’s atmosphere.

Today argon is produced primarily by air condensation at low temperature. Then, it is separated from oxygen and nitrogen.

In addition, it is possible to produce Argon gas from black metallurgical plant products, or from emissions during the production of NH3.

Depending on different usage requirements, Argon is usually supplied in many purity levels: Ar 4.8, Ar 5.0, Ar 5.3.

As mentioned above, argon gas is widely used in life, production and research, it is non-toxic and does not harm human health.

In particular, it is safe to use because it does not explode, but it is heavier than air, so it is easy to accumulate in poor air places. This heavy gas accumulation often causes welders to be easily suffocated due to lack of oxygen.

When inhaled a lot of argon gas, welders are more susceptible to dizziness, headache, discomfort and even suffocation. Sometimes, direct contact with liquid can result in cold burns.

Nausea, vomiting, loss of consciousness, and unconsciousness will occur If people inhale excessive argon gas.

When the argon gas reaches a concentration as high as 75% it can be fatal in just a few minutes and the body will be weakened, then loss of consciousness, convulsions, deep coma and rapid death will occur.

Therefore, it is necessary to monitor and maintain the oxygen ratio in the workplace not fall below 19% while using argon gas.


  • In case eyes directly contact argon: Your body is normal, there is no effect to your health.

  • In case skin contact skin (being wired to the skin): no effect to the body or health.
  • In case of inhalation argon exposure (inhalation of argon vapor or gases): if suffocated and difficult to breathe, you can quickly support oxygen to increase oxygen supply to the body.
  • Accident occurred from the gastrointestinal tract: absolutely no effect.

Measures to prevent inhalation of excessive argon gas:

In work area, it must be ventilate all the time, the measures to isolate and to reduce the concentration of argon vapor and gases should be taken or the welder’s working hours in low air has to be limited.

Measures and conditions have to be applied when storing argon: avoid storing the gases at too high temperatures and avoid impacting gas cylinders during transport.
Measures and conditions have to be applied when using the gases are to check and close the safety valve regularly.

As long as you take these preventive measures well, you completely do not have to worry while working with argon gases because it is much safer than other gases. So, if you have any demands for argon, you should find a reputable supplier of argon gas.
