![]() Shielding gases are inert or semi-inert gases used in various MIG and TIG welding practices to protect the weld area from water vapor and oxygen. One other essential use for this gas can be seen as a shielding gas in welding. Like 99.9999% pure helium, this helium is also considered to be research grade and is used in many applications related to chromatography and semiconductor processing. At this time, helium is the only medium that is cold enough to promote superconductivity in metal alloys.Īlso called, ‘trace analytical grade’, this helium is one of the purest available on the market. Such a lower temperature is essential because it enables superconductivity - leading to an electrical conductor without resistance, which means that there are no losses. This is because they require superconductive magnets that must be kept at a temperature of below 10 Kelvin in order to function. Research grade liquid helium is also an essential part of any MRI machine. It also plays an important role in energy transfer as it can be used as a direct heat transfer medium to help maintain a certain temperature for the gas phase reactants and the solid wafer. Because helium has such a low mass, it's possible to integrate specialized mass control that can be used to sense, measure, and manage the amount of chemical vapor dispensed. This is because semiconductor chips are manufactured on base silicon wafers using deposition and etch chemical reactions in the gas phase, resulting in thin layers of different materials on the wafer surface. The closest you can get to 100% pure helium, this grade is essential for manufacturing semiconductor chips. This means that it is absolutely essential for the daily functioning of many daily activities and items, from welding and manufacturing, to refrigeration and cooling, and even in the airbags in our cars. Helium’s natural characteristics are what gives it so much utility across such a wide range of uses and industries. ![]() Breathing mixtures to help reduce densityĪ Slightly-More In-Depth Look at the Uses of Helium.Lab research where higher purity gases are not necessary.The below chart outlines in brief some of the most essential uses for this highly-desirable gas. While that isn’t exactly the case, it is still true that it’s absolutely indispensable for the happy and normal functioning of many, many parts of our lives oftentimes without us even realizing it.ĭepending on the purity of the helium, it can have a number of different uses across medical, life sciences, industrial / manufacturing, and many others. ![]() And as one of the most abundant elements in our atmosphere, you might think it to be one of the most available. ![]() Ever had an MRI? Or used a smartphone? Then you’ve got helium to thank for it. ![]()
