Apatite is a group of phosphate minerals, usually hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH −, F − and Cl − ion, 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 ...

What is Apatite? 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.

2025年1月7日 · Apatite is a group of phosphate minerals commonly found in a variety of geological environments. It is an important mineral due to its role in the formation of bones and teeth in living organisms, and is also used as a source of phosphorus for fertilizers.

Apatite is named for the Greek word apate, which means "deceit", since Apatite is similar in appearance to many other minerals. Apatite describes a group of similar isomorphous hexagonal phosphate minerals. The primary Apatite group includes Fluorapatite, Chlorapatite, and Hydroxylapatite.

Apatite is a member of a group of structurally related minerals having compositions symbolized A5 (B O 4) 3X, in which A is a metal, commonly calcium or lead; B is phosphorus, vanadium, or arsenic; and X is chlorine, fluorine, or hydroxyl.

Apatite is a concentration of many different minerals and trace elements such as fluorite, magnesium, calcium, and iron. It forms in the hexagonal crystal structure and is most commonly found with the chemical composition Ca5 (PO4)3 (F,Cl,OH); although certain variables and trace elements may alter the composition of specific specimens.
