Suppose I fill a vacuum chamber with 99% oxygen, then pull a vacuum on it down to 10 pascal absolute. If I then vaporize aluminum (for vapor deposition), will the aluminum bind with the remaining oxygen and create say a 0.1 pascal vacuum?
I'm not a chemist or a physicist, but it seems logical that the heavier (and high melting point) aluminum oxide molecules would collect on the walls and floor of the container resulting in a high vacuum mainly containing vaporized aluminum.
I am looking to experiment with aluminum vapor deposition and want to avoid buying a diffusion or turbo molecular pump. Seems like this should work, but I have not found any documentation on it. I'm not looking for optics quality here, so maybe high vacuum is not an issue in the first place.
Let me know if you guys think I should post this on the Physics SE instead. Thanks!
