Chemist for uranium nuclear fuels. A substance would only burn in a vacuum if it contained an oxidizer. There has to be an oxidizer for there to be fire. That doesn't mean that it requires oxygen, just a substance that facilitates the removal of electrons. 1 person found this useful.
I heard that you can not put out a thermite reaction because it is self oxidizing and does not need ambient oxygen to burn. If this is true i do not see any reason why you could not have a thermite reaction in a vacuum. That's correct. Once ignited, there's no practical way to stop it.
