Mineral dust is mainly constituted of the oxides (SiO 2, Al 2 O 3, FeO, Fe 2 O 3, CaO, and others) and carbonates (CaCO 3, MgCO 3) that constitute the Earth's crust.The composition of mineral dust, usually named in atmospheric sciences as mineralogy composition, is relevant for different physical and chemical processes in the atmosphere, for example, oxides with iron have an effect in the ...

In 1963, this definition was refined as the space occupied by 10 pounds of distilled water of density 0.998 859 g/mL weighed in air of density 0.001 217 g/mL against weights of density 8.136 g/mL (the original "brass" was refined as the densities of brass alloys vary depending on metallurgical composition), which was calculated as 4.546 091 879 ...
Prismatine is an orthorhombic-dipyramidal mineral containing aluminium, boron, fluorine, hydrogen, iron, magnesium, oxygen, and silicon. It forms a solid solution series with kornerupine . [ 4 ]
Pristane is a natural saturated terpenoid alkane obtained primarily from shark liver oil, from which its name is derived (Latin pristis, "shark").It is also found in the stomach oil of birds in the order Procellariiformes and in mineral oil and some foods. [2]
Celestine (the IMA-accepted name) [6] or celestite [1] [7] [a] is a mineral consisting of strontium sulfate (Sr S O 4). The mineral is named for its occasional delicate blue color. Celestine and the carbonate mineral strontianite are the principal sources of the element strontium, commonly used in fireworks and in various metal alloys.
Ultrapure water (UPW), high-purity water or highly purified water (HPW) is water that has been purified to uncommonly stringent specifications. Ultrapure water is a term commonly used in manufacturing to emphasize the fact that the water is treated to the highest levels of purity for all contaminant types, including: organic and inorganic compounds; dissolved and particulate matter; volatile ...
Phytane is a non-polar organic compound that is a clear and colorless liquid at room temperature. It is a head-to-tail linked regular isoprenoid with chemical formula C 20 H 42. [2]
