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 ...
Water Ritual #1: An Urban Rite of Purification is a 1979 short experimental film directed, produced, written, and edited by Barbara McCullough. It is McCullough's first film and is generally considered a pioneering experimental film by an African-American woman. [ 1 ]
In mineralogy, an inclusion is any material trapped inside a mineral during its formation. In gemology , it is an object enclosed within a gemstone or reaching its surface from the interior. [ 1 ] According to James Hutton 's law of inclusions, fragments included in a host rock are older than the host rock itself.
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 main constituent, and also the most reactive phase, of calcium aluminate cements is the monocalcium aluminate (CaAl 2 O 4 = CaO · Al 2 O 3, also written as CA in the cement chemist notation). It usually contains other calcium aluminates as well as a number of less reactive phases deriving from impurities in the raw materials.
Agua Bendita (lit. ' Holy Water ') is a 2010 Philippine romantic fantasy religious-drama television series based on the Liwayway Komiks comic book series of the same name created by Rod Santiago and directed by Malu L. Sevilla, Claudio "Tots" Sanchez-Mariscal IV, Don M. Cuaresma and Jojo A. Saguin.
