Helium is a crucial element in various technological applications. As a noble gas, it possesses unique properties that make it indispensable in many industries.
One of the primary uses of helium is in cooling superconducting magnets in MRI machines. This application relies on helium\“s extremely low boiling point, which enables it to maintain the ultra-low temperatures required for superconductivity.
Helium is also vital in the semiconductor manufacturing process. It serves as a protective atmosphere during the production of silicon wafers, preventing oxidation and contamination that could compromise the quality of electronic components.
In the aerospace industry, helium is used to pressurize rocket fuel tanks and purge fuel systems. Its inert nature and low density make it ideal for these critical safety applications.
The welding industry utilizes helium as a shielding gas for arc welding. When mixed with other gases, it helps create stable arcs and produces high-quality welds on various metals, including aluminum and stainless steel. |
