You speak of $alumina, A l_{2} O_{3}$ $"alumina, "Al_2O_3$ .

Explanation:

Aluminum generally forms $A l^{3 +}$ $Al^(3+)$ ions.

Oxygen generally forms $O^{2 -}$ $O^(2-)$ ions.

So when the metal and the non-metal make music together they form a neutral compound, i.e. $A l_{2} O_{3}$ $Al_2O_3$ (i.e. $2 \times 3 - 3 \times 2 = 0)$ $2xx3-3xx2=0)$ .

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