A calcium–aluminium-rich inclusion or Ca–Al-rich inclusion (CAI) is a submillimeter- to centimeter-sized light-colored calcium- and aluminium-rich inclusion found in carbonaceous chondrite meteorites. The four CAIs that have been dated using the Pb-Pb chronometer yield a weighted mean age of 4567.30 ± 0.16 Myr.
The following inclusion types can also be found in aluminium alloys: alumina needles (Al 2 O 3), nitrides (AlN), iron oxides (FeO), manganese oxides (MnO), fluorides (Na 3 AlF 6, NaF, CaF 2, …), aluminium borides (AlB 2, AlB 12), borocarbides (Al 4 C 4 B).
