Comment Anything you can do Argon do better (Score 1) 109
Well, to continue the song metaphor, no, it can't. But which applications can use a replacement gas?
Nitrogen is good for cooling, but helium is better. Nitrogen is also fairly unreactive. Argon is better, and I gather helium is slightly better still. Both can be extracted from the air.
MRIs need newer materials to use nitrogen, but I think they can. Why can't semiconductors use nitrogen or argon?
