The basic formula for apatite is Ca5 (PO4)3X, where X can be any one of several ions, including OH-, F-, Cl-, or a combination of these. Apatite can also contain various trace elements and impurities, …
Empirical Formula: Ca 5 (PO 4) 3 (OH) 0.33 F 0.33 Cl 0.33. Environment: Apatite is now a group name for a series of related minerals. IMA Status: Not Approved IMA. Locality: …
Look for Apatite Supergroup images on Google. A supergroup that includes minerals with a generic chemical formula #IX#M12#VII#M23 (#IV#TO4)3X (Z = 2). A large number of …
Click the show button to view. 'Apatite' is a field term for unidentified calcium phosphate members of the apatite group. Most 'apatite' is fluorapatite, whereas hydroxylapatite is …
The primary Apatite group includes Fluorapatite, Chlorapatite, and Hydroxylapatite. The extended Apatite supergroup describes additional minerals such as Pyromorphite, …
The process can be applied if volatile iodides (from that they are also termed as the iodine process) of metal were formed and if the metal has higher melting point than the dissociation temperature of …
Apatite is the name of a group of phosphate minerals with similar chemical compositions and physical properties. They are an important constituent of phosphorite, a rock mined for its phosphorus content and used to make fertilizers, acids, and chemicals. Apatite has a relatively consistent hardness and …
A group in the Apatite Supergroup which includes hexagonal and pseudohexagonal phosphates, arsenates and vanadates containing the same species-defining cation at both the M1 and M2 sites (Pasero et al 2010).
The spectroscope is a good diagnostic tool in separating apatite from gemstones as tourmaline and topaz. Blue apatite will, usually, show a rare earth spectrum line in the blue (praseodymium). Blue-green stones may …
