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 ...
oxides (simple — FeO, MnO, Cr 2 O 3, SiO 2, Al 2 O 3, TiO 2 and others; compound — FeO·Fe 2 O 3, FeO·Al 2 O 3, FeO·Cr 2 O 3, MgO·Al 2 O 3, 2FeO·SiO 2 and others; The majority of inclusions in metals are oxides and sulfides since the content of phosphorus is very small. Silicates are very detrimental to steels, especially if it has to ...
Al-Ca composite is a high-conductivity, high-strength, lightweight composite consisting of sub-micron-diameter pure calcium metal filaments embedded inside a pure aluminium metal matrix. The material is still in the development phase, but it has potential use as an overhead high-voltage power transmission conductor . [ 1 ]
Reaction with Al 2 I 6 yields subvalent halide species; reaction with As 4 tBu 4 yields As-Al bonds. [6] When reacted with transition metal-cyclopentadienyl complexes such as NiCp 2 , it offers a straightforward pathway to compounds containing aluminium-transition metal bonds, which has great potential for important catalytic reactions.
