You speak of #"alumina, "Al_2O_3#.

Explanation:

Aluminum generally forms #Al^(3+)# ions.

Oxygen generally forms #O^(2-)# ions.

So when the metal and the non-metal make music together they form a neutral compound, i.e. #Al_2O_3# (i.e. #2xx3-3xx2=0)#.

The ionic bonding is so strong (due to charge magnitude) in this material that it is reasonably insoluble.
