	Helium's industrial uses include as a pressurizing and purge gas, as a protective atmosphere for arc welding, for cryogenic cooling, and in processes such as growing crystals to make [[silicon]] wafers, as well as a lifting gas in balloons and airships.		Helium's industrial uses include as a pressurizing and purge gas, as a protective atmosphere for arc welding, for cryogenic cooling, and in processes such as growing crystals to make [[silicon]] wafers, as well as a lifting gas in balloons and airships. He<sup>4</sup>, having an even number of particles, has a total spin of a whole number, meaning that it can form a Bose-Einstein condensate, useful for studying quantum mechanics. He<sup>3</sup> can also do this, but needs to be cooled down more for the required Cooper pairs, since its spin is not a whole number.
