WebLiquid helium is unique among all elements in that it can reach ultra-cold temperatures, approaching absolute zero (-273.15°C). Research conducted at these low temperatures has led to discoveries in superconductivity that have led to many applications, including the Maglev high-speed train. WebUses of Helium. The primary use of Helium goes in altitude research and meteorological balloons. It is utilized as an inert protective gas in autogenous welding. It is the only cooler capable of declining temperature lower than 15K (-434ºF). Helium is also used in the production of germanium crystals and silicon crystals.
