I'm a physician, and quite ignorant about chemistry.
I'm wondering if there are two gases that link (strongly) together to produce solid matter.
And if it'd be possible to have those gases pure, not mixed with other gases (how many impurities per million).
Thank you very much for your *delete me*!

Check ammonium chloride.

I cannot find anything...
Essentially I'm looking for a reaction between a gas and something else (whatever), that has only solid products.

Ammonium chloride is a solid that can be produced using two gases - ammonia and hydrogen chloride. You mix two gases and solid precipitates out of the gaseous phase.

does all the gas vanishes? I mean, if I put a correct amount of reacting gases in a sealed box, may I obtain the vacuum?

Interesting idea.  It's definitely possible - I'm not sure if ammonium chloride sublimes under very low pressure.  A problem you'd probably run into is how to get the two gases into the container and get the container sealed before they react - the reaction begins pretty much immediately.  What purpose is this for out of curiosity?

I'm studying cryogenic devices (1st year of my master), wondering how to improve the current technology.

No. But compare http://en.wikipedia.org/wiki/Getter

interesting... I'm gonna search about getters in literature. Didn't know about their existence. Thank you!
