Please explain Niggli notation -- specifically for Al2O3 (corundum). How do you you write the composition of corundum in Niggli notation?
The Niggli-notation of Al2O3 can be written as follows.
The explanation is provided in the right of the Curly brackets in the above notation.
Al2O3 = 2Al + 3O
= 1Al + (3/2)O
= 1Al + (3/2 + 1)O (If you increase the number of oxygens by 1, then the charge on the whole species increases by -2)
