Nitrogen and That Crazy Titanium
I have heard that Titanium is the only element that is able to burn in a pure Nitrogen atmosphere. My question is, how do you ignite the Titanium, is
it just heated until a certain temperature? What is that certain temperature? If anyone has any other information about this or any other wierd
attributes that some elements have I would greatly appreciate it if you would share them with me.

If I'm not mistaken Mg shares this same attribute. With Magnesium, what I believe is done is the Mg is lit out side of the nitrogen, and then is
inserted into the nitrogen. If you just heated, It would probably combine with the Nitrogen to make Titanium Nitride.

Well, if that's where you're going, Magnesium burns underwater too!
As for weird elemental attributes, how about this. There are 4 ferromagnetic elements. You are probably familiar with Iron, Cobalt and Nickel, but
have you heard of Gadolinium? A rare earth, it has a rather unique ferromagnetic transition temperature. It is highly magnetic below about 66 degees F
(292 K - hope I did the conversion right), but looses it's magnetism above it. I've always thought that was kinda neat!
More commonly known is that if you pour very hot molten sulfur into water to cool it quickly, it stretches like plastic for awhile afterwards.
But wait, there's more... just read!

Lithium will actually react more with atmostpheric nitrogen then oxygen at normal temperature and pressure so it could easily burn in it. Lithium
nitride is a almost black coating that develops on lithium metal shortly after you remove it from the oil. Great stuff, great stuff!

I was wondering why the stuff on my Li was black .
Anyone know what the combustion products of Ti or Mg burning in Nitrogen are ? nitride or a mix with something else ? (can they form any other
compounds without any other element ? .

AFAIK they only form the nitrides when burning in a pure nitrogen atmosphere. A good test is to put a small bit in water and see if some ammonia
evolves.
Mg<sub>3</sub>N<sub>2</sub> + 6H<sub>2</sub>O <sup><u> </u></sup>>
3Mg(OH)<sub>2</sub> + 2NH<sub>3</sub>
Also notice that this happens because of the common ion effect (in this case it's OH-):
NH<sub>4</sub>OH <u> <<strike> </strike></u><sub>> </sub>
NH<sub>3</sub><b>·</b>H<sub>2</sub>O
