How to make argon gas
Industrial making argon gas The current method of obtaining argon in the industry is to distill the air. A condenser can be used to liquefy the oxygen at a boiling point of 90.2 K, and after cooling to remove liquid oxygen, liquefy argon at a boiling point of 87.3 K and finally leave nitrogen at a boiling point of 77.35 K. Argon gas currently manufactured in this way is as high as 700,000 tons / year worldwide.
Other methods, in addition, use potassium-40 decay to make argon, but the efficiency of this method is not high because the half-life of potassium-40 is as long as 1.26 × 10 9 years old and is not commonly used. If you want to make radioactive isotopes of argon, you have to rely on cyclotrons and heavy ion accelerators to convert other elements into argon isotopes.
