Apatite is the most common phosphate mineral, and is the main source of the phosphorus required by plants. The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite. (These biological Apatites are almost exclusively the Hydroxylapatite type.) Chemical Formula.

Apatite is a group of phosphate minerals, usually referring to hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH −, F − and Cl − ions, respectively, in the crystal.The formula of the admixture of the three most common endmembers is written as Ca 10 (PO 4) 6 (OH,F,Cl) 2, and the crystal unit cell formulae of the individual minerals are written as Ca 10 (PO 4) 6
Mineral Type Apatite. "Apatite" is a field term for unidentified calcium phosphate members of the apatite group. Most "apatite" is fluorapatite, whereas hydroxylapatite is much less common and chlorapatite is very rare. "Apatite" crystals are short to long hexagonal prisms [0001], with {1010} and {1011} dominant; also thick tabular {0001
Blue apatite is a prized mineral specimen by rock collectors for its vibrant royal blue color. Most of the apatite rock mined throughout the world is used to produce phosphate fertilizer. It is also used to produce animal feed supplements, phosphoric acid,

The study of the oldest surviving rock suites is crucial for understanding the processes that shaped the early Earth and formed an environment suitable for life. The metasedimentary and metavolcanic rocks of the early Archean Isua supracrustal belt contain abundant apatite
Jan 03, 2020 Apatite is an interesting gemstone with an unusual mineral make-up. Apatite is actually a wide group of different but similar minerals found all over the world usually composed of calcium phosphate (the material that makes our teeth and bones) plus fluorine, chlorine or hydroxyl.
Jun 04, 2021 Calcium apatite is a mineral commonly used in fertilizer and is also a major component of bones and teeth. The researchers formed a “sponge” in the ground by injecting two inexpensive and nontoxic chemicals, calcium citrate and sodium phosphate, into a well especially designed for injecting solutions underground at the former uranium mill.
APATITE (Calcium (Fluoro-, Chloro-, Hydroxyl-) Phosphate) Chemistry: Ca 5 (PO 4) 3 (OH,F,Cl), Calcium (Fluoro, Chloro, Hydroxyl) Phosphate. Class: Phosphates. Group: Apatite. Uses: as a source of phosphorous to be used in fertilizer, rarely as a gemstone and as a mineral specimen. Specimens. Apatite is actually three different minerals
Apatite, any member of a series of phosphate minerals, the world’s major source of phosphorus, found as variously coloured glassy crystals, masses, or nodules. If not for its softness (Mohs hardness 5, compared with the 7 to 9 of most gems), apatite would be a popular gemstone; much of the material

Blue Apatite Properties. Blue apatite is a form of the mineral group that was named apatite in 1786, although the strict definition of this mineral formation was not determined, as it is used today, until 1860. The mineral apatite comes from a Greek word meaning “to deceive,” because of its unusual origins.

Apatite is a calcium–phosphate mineral, and because P has no stable isotopes, the uptake dynamics can only be studied via the Ca ion (or potentially the 18 O/ 16 O in the phosphate group). In most rocks and soils apatite is the sole primary P source.

Blue Apatite Meanings, Zodiacs, Planets, Elements, Colors, Chakras, and more. Apatite is a calcium phosphate mineral found in a variety of colors such as yellow, blue, green, gray, and brown. The most important colors for metaphysical use are blue, green, and gold. Apatite was first discovered in 1786 by A.G. Werner ,but it’s name came from the Greek word meaning “to deceive”,due to
Mar 01, 2019 Although the discovery of apatite in mineral form was in 1827 the naming and renaming of the species and sub species, has been ongoing for the last 190 years .According to the International Mineralogical Association Commission on New Minerals, Nomenclature and Classification (IMA- CNMNC), currently there are only three minerals of the apatite group, chlorapatite, fluorapatite and
Apatite Physical Properties. It is best known for its use as an index mineral with a hardness of 5 in the Mohs Hardness Scale. It is usually green in color, but can be yellow, brown, blue, purple, pink, or colorless. These colors are often so vivid that it has frequently been cut as a

Dec 22, 2014 Bone mineral is the reservoir for carbon dioxide in the body and maintains the concentration of mineral ions in body fluids at homeostasis. The detailed structure of bone mineral has remained obscure more than 80 years after publication of the basic apatite structure, because of the nanoscale size and poor quality of bone mineral crystals.
Apatite is identified by the chemical formula Ca 5 (PO 4) . It forms in hexagonal crystals and is a rock phosphate mineral. Apatite can exist in many different forms, along with other minerals, as long as the base of apatite calcium (Ca 5) and phosphorous (PO4) exist together. There are three common forms of apatite that appear in nature.
Apatite is now a group name for a series of related minerals. IMA Status: Not Approved IMA : Locality: Common world wide. Link to MinDat Location Data. Name Origin: Named in 1788 from the Greek apatao "I am misleading." Name Pronunciation: Apatite : Synonym: Davisonite mixture with crandallite : Dennisonite mixture with crandallite
