What are the oxidation and reduction reactions of Aluminium(III) oxide?

I need the detailed process of the redox reactions of aluminium(III) oxide! I'm struggling to find it on google.

I'm assuming you mean the half reactions for the production of aluminum oxideAl - Al3+ + 3e- O2 + 4e- - 2O2- Balance electrons: 4(Al - Al3+ + 3e-) 3(O2 + 4e- - 2O2-) 4Al - 4 Al3+ + 12 e- 3O2 + 12 e- - 6O2-
