What Is The Scope Of Application Of Helium?

Helium is a product with a wide range of applications, but this gas is a very scarce resource in China, so the price is generally high. Let us introduce the application range of this product in detail below.
Helium can also be used as a shielding gas in atomic reactors and accelerators, lasers, rockets, smelting and welding, it can also be used to fill light bulbs and neon tubes, and it is also used to make foam plastics.
Due to the low solubility of helium in the blood, it can be added to oxygen as a diver's breathing gas. Is it dangerous for helium? Helium is used for deep sea breathing gas, it can be seen that helium is not dangerous!
The temperature of liquid helium is close to absolute zero (-273°C), so it is used as a superfluid in superconductivity research to make superconducting materials. Liquid helium is also commonly used as a coolant and refrigerant.
In medicine, helium is used in argon-helium knife to treat cancer.
Helium is also used as a component of artificial atmospheres and laser media.
Helium can be used to preserve corpses, and the gas in Mao Zedong's crystal coffin is helium.
