How is Helium used in the semiconductor industry?
Super cooling in super computers and MRI machines. Materials conduct electricity faster at colder temperatures and helium is the gas with the second lowest temperate where it turns into a liquid. But, unlike hydrogen helium is not flammable. The accident of the Hindenburg keeps people from using liquid hydrogen. Helium boiling point: −268.93 °C, −452.07 °F Hydrogen boiling point: −252.87 °C, −423.17 °F The reason why the boiling points are so low depends on the atomic size, the larger the atom the higher its boiling point is, with some exceptions like mercury. This is just a general trend, not a rule. Remember that absolute zero; an unreachable point is at -270 degrees C, so liquid helium is very close to absolute zero. According to Wikipedia: http://en.wikipedia.org/wiki/Super_condu… “Superconductivity is a phenomenon occurring in certain materials at extremely low temperatures, characterized by exactly zero ele
