Apatite is the name given to a group of phosphate minerals, usually referring to hydroxylapatite (or hydroxyapatite), fluoroapatite (or fluorapatite), and chloroapatite (or chlorapatite).They are named for the presence of hydroxide (OH-), fluoride (F-), and chloride (Cl-) ions, respectively, in the crystal lattice. These three forms of apatite …

Made from a common group of minerals containing a calcium phosphate base, Apatite reminds us that truly knowing oneself is the key to opening up the doors of the universe, a place where anything is possible. Speaking of possibilities…Here’s the game changer in harnessing the full potential of Apatite.

Apatite is actually three different minerals depending on the predominance of either fluorine, chlorine or the hydroxyl group. These ions can freely substitute in the crystal lattice and all three are usually present in every specimen although some specimens have been close to in one or the other.

Calcite

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.)

Apatite is a mineral that belongs to the group of phosphates formed by the combination of phosphorus, oxygen and cations. Among its chemical composition has fluorine, chlorine and foreign anions. Precisely because of that fluoride composition, apatite is present in our bones and our teeth.

El nombre de apatita deriva del griego apate (equivocarse) ya que puede ser confundido fácilmente con otros minerales como el berilo o la turmalina. Sinónimos utilizados para este mineral en español son: apatita, agustita, asparagolita, augustita, kietyogita, kietyöita y sombrerita.

Apatite is a very common mineral but transparent gemstone-quality is extremely rare. Despite the fact that is the defining mineral for 5 on Mohs scale of hardness, the gemstone remains virtually unknown to most, and is seldom found in jewelry stores.

A apatita (apatite, em Portugal) é um mineral do grupo dos fosfatos, com as seguintes variantes: hidroxiapatita, fluorapatita, e clorapatita, assim nomeados por causa de altas concentrações de íons Hidróxido(OH-), Fluoreto(F-), e Cloreto(Cl-), respectivamente, em sua estrutura cristalina.Sua fórmula geral (que apenas explicita a sua composição essencial) é Ca 5 (PO 4) 3 (OH, F, Cl).

APATITE BACKGROUND INFORMATION. Apatite is the name given to a group of three related minerals the most common of which is fluorapatite(Ca 5 (PO 4) 3 F), and more rarely clorapatite(Ca 5 (PO 4) 3 Cl) and hydroxylapatite(Ca 5 (PO 4) 3 OH).
