Apatite: The mineral apatite information and pictures

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 Wikipedia

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 mineral Britannica

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.

Calcium Phosphate Mineral an overview ScienceDirect Topics

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.

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.
