WebThere are many mixed oxides containing aluminium where there are no discrete or polymeric aluminate ions. The spinels with a generic formula A2+ B3+ 2O2− 4 that contain aluminium as Al 3+, such as the mineral spinel itself, MgAl 2 O 4 are mixed oxides with cubic close packed O atoms and aluminium Al 3+ in octahedral positions.
