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.
Krotite was reported in 2011 [3] in a calcium-aluminium-rich inclusion (CAI) in the carbonaceous chondrite meteorite NWA (North West Africa) 1934, which landed in Morocco. [4] The mineral name was approved by the International Mineralogical Association (IMA 2010-038) [ 5 ] and honors Alexander N. Krot, a researcher in cosmochemistry at the ...
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 ...
BATON ROUGE, La. — Kareem Badawi, the University of Alabama student killed in the New Orleans terrorist attack, was laid to rest Friday as his father heartbreakingly recalled how excited his son ...
Hibonite also is a common mineral in the Ca-Al-rich inclusions found in some chondritic meteorites. Hibonite is closely related to hibonite-Fe (IMA 2009-027, (Fe,Mg)Al 12 O 19)) an alteration mineral from the Allende meteorite. [4] Hibonites were among the first minerals to form as the disk of gas and dust swirling around the young sun cooled. [5]
A federal judge said Kraft Heinz must face a proposed nationwide class action alleging that it defrauded consumers by claiming its Kraft macaroni and cheese, one of its best-known products ...
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 ]
The House-passed Social Security Fairness Act enjoys rare bipartisan support on Capitol Hill, yet the odds of it getting enacted are growing smaller with each passing day.
