Anyone has the structure of it? or link?

 

And what is the pH value of this molecule?

Al2O3 (corundum) is Orthorombic in crystal structure, no idea about it`s ph though, sorry.

 

edit: this maybe helpfull though: http://www.webelements.com/webelements/compounds/text/Al/Al2O3-1344281.html

Thx, but i need to draw the structure out, headach v_v.

 

Does anyone has the drawing structure?

i think the al are sharing an oxygen and 2 other oxygens are on the ends.

interestingly, ruby is aluminum oxide with slight traces of chromium salts and sapphire is aluminum oxide.

are emeralds aluminum oxide too? and what of other gems, I dont really know what any of them are made of 'cept diamonds (carbon of course)...
