AshSmall is it reactive or is it such a fine powder?
I comes off as a fine powder that burns brighter than magnesium.
I once heard about someone who was doing a 'home job' after hours in a machine shop. He was machining what he thought was a piece of aluminium in a lathe at high speed using a ceramic tool. It turned out to be magnesium, and the swarf was coming off so fast, the friction from the ceramic tool caused it to get so hot it caught fire (he was machining it dry, with no coolant). All that magnesium swarf burning must have looked pretty impressive! Anyway, after they got the fire extinguishers on it and cleaned up the mess as best they could, he had a hard time the next morning trying to explain to the boss why their new lathe was covered in this green slime stuff that they couldn't clean off.
Ti also burns in oxygen when it is hot. Molten Ti will explode if it comes into contact with oxygen and, I think, nitrogen. It is cast in a vacuum furnace, after purging with argon.
One of the ships in the Falklands war had an aluminium superstructure which literally caught fire after it was hit. A person I went to school with was on board, but below decks as he worked in the galley. A lot of people were killed. (HMS Sheffield)

Did he live? And hm. It seems like, once you set Ti on fire, there's no stopping it, as air has all the necessary ingredients for it!
