Apatite is the name of a group of phosphate minerals with similar chemical compositions and physical properties. Hardness: 5.0. Apatite's various colors are often due to the presence of rare earth elements or natural irradiation. In addition to traditional topics - descriptions of major structural groups, methods of mineral analysis, and the paragenesis of mineral species - this volume embraces such subjects as asbestiform minerals, minerals found in caves and in ... Chlorapatite and carbonate-apatite are comparatively rare. Mineral Properties. Hydroxyapatite, also called hydroxylapatite (HA), is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4) 3 (OH), but it is usually written Ca 10 (PO 4) 6 (OH) 2 to denote that the crystal unit cell comprises two entities. There are three common forms of apatite that appear in nature. Apatite. 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. The phosphorous in apatite (notice the "P" in the formula) makes this mineral family an important fertilizer. The formula of the admixture of the three most common endmembers is written as Ca10(PO4)6(OH,F,Cl)2, and the crystal unit cell formulae of the individual minerals are written as Ca10(PO4)6(OH)2, Ca10(PO4)6F2 and Ca10(PO4)6Cl2. This book is a useful resource for biomaterials scientists and engineers, as well as for clinicians and the academic community. Cal Apatite Bone Builder Forte is an excellent bone support formula that features extra MCHC (1.9 g per serving). 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. Hydroxyapatite is … Description.

Variety of the Apatite group where the phosphate radical (PO4) is partially replaced by a carbonate radical (CO3). It is the mineral that makes up tooth enamel in all vertebrate animals. Bone mineral, for example, is constituted of nanocrystalline nonstoichiometric apatite, and the production of “analogs” through a variety of methods is frequently reported. Apatite is the defining mineral for 5 on the Mohs scale. It has a wide variety of colour. Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. 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 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. Streak: white. Description. Most "apatite" is fluorapatite, whereas hydroxylapatite is much less common and chlorapatite is very rare. Ca5FO12P3. Aquamarine (up to 1.2 cm) in sky blue color in combination with peach Pink Apatite (2.7 cm) on the Muscovite bouquet. A large number of ions may occupy the key sites in the structure, and thus the possible number of distinct minerals is large. Found insideThese are described in this publi cation with all the details required for practical application. Neither the editors nor NIST wish to endorse any single approach. This comprehensive formulation also supplies beneficial levels of … Kuhn, in Encyclopedia of Materials: Science and Technology, 2001 3 The Chemical and Physical Structure of Bone Mineral. It has a chemical formula of Ca5(PO4,CO3)3(OH,F). Calcium phosphate apatites are inorganic compounds encountered in many different mineralized tissues. Three species named according to the prevalent anion: Chlorapatite Ca5 (PO4) 3 Cl This book comprises papers resulting from the 1st International workshop ‘Minerals as Advanced Materials I’. It is intended as an exchange of ideas between mineralogists and material scientists. To calculate mineral formula requires transforming weight percent into atomic percent or molecular percent MINERAL FORMULA CALCULATIONS (cation … Some of the calcium minerals are as under: (1). Apatite Discovered in 1860, this mineral is named from the Greek word "to deceive" as it was often confused with other minerals. Transparency: Transparent to translucent. Healed fractures, hollow growth tubes. As a source of phosphorous, the primary use of Apatite is in the manufacture of … The two volumes of the Handbook of membrane reactors draw on this research to provide an authoritative review of this important field. Ca(F, Cl) 2.As secondary admixtures apatite sometimes contains up to 10 percent oxides of manganese, strontium, or rare earth elements; less than 1 percent sodium, potassium, or barium frequently replaces part of the calcium. Chemical Formula: Ca 5 (PO 4) 3 (F,Cl,OH) Color (s): blues, greens, blue green can be colorless, pink, or brown. Carbonate apatite. The goal of this book is to provide readers with a broad appraisal of topics in global advancements in theoretical and experimental facts, and practical applications of nano-HAp materials based on their synthesis, properties, prospects, and ... apatite: ( ap'ă-tīt ), Generic name for a class of minerals with compositions that are variants of the formula D 5 T 3 M, where D is a divalent cation, T is a trivalent tetrahedral compound ion, and M is a monovalent anion; calcium phosphate apatites are important mineral constituents of bones and teeth.
