I did military engineering for some time so we worked with a lot of Titanium, but when machining it we were always told to remove scraps ASAP and bag them up because if a single spark from a welding torch got on the pile then it would go up in flames and can even explode. To demonstrate this the instructor got a pile of titanium shavings and lit them on fire. We were never instructed why this happens and googling it I could only find stuff about titanium powder in pure oxygen or the melting point of titanium.

Oxygen is lonely – it has space in its heart (outer shell) for love (electrons).
Titanium is lonely too. But its heart is too big and full of love (electrons) to give.
If Titanium and Oxygen meet each other and fall in love, titanium gives some of its electrons to Oxygen and they form a new relationship that the media nicknames “Titanium Dioxide”.
Well TiO² wants to settle down now, they’re all nicely bonded so they don’t need all the energy they used to have, so they get rid of it – in the form of heat.
Well that heat energy is provocative, it gets the people going. It gives the other Titanium and Oxygen a push to fall in love as well. Awww.
