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). Bone ash (Ca 3 (PO 4) 2) sometimes added to patch cracks in the trough can be found as ...

Al 2 Si 2 O 7, (Al 2 O 3 ·2SiO 2), called metakaolinite, formed from kaolin by heating at 450 °C (842 °F). [5] Al 6 Si 2 O 13, (3Al 2 O 3 ·2SiO 2), the mineral mullite, the only thermodynamically stable intermediate phase in the Al 2 O 3-SiO 2 system at atmospheric pressure. [6] This also called '3:2 mullite' to distinguish it from 2Al 2 O ...
3CaO·Al 2 O 3 ·Ca(O,Cl 2) · 11 H 2 O. A simplified chemical composition with only Cl – in the interlayer, and without OH –, as: Ca 2 Al(OH) 6 (Cl) · 2 H 2 O. can be also written in cement chemist notation as: [1] 3CaO·Al 2 O 3 ·CaCl 2 · 10 H 2 O. Friedel's salt is formed in cements initially rich in tri-calcium aluminate (C 3 A ...
