The polymer and the mineral were ground separately, but also together (co-grinding), in the case of mixtures containing between 10 and 40 wt.% of apatite. The co-grinding time was varied from 10 min to 10 h.Powder samples were taken from different regions of the chamber at various times to be analysed.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 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. The mineral was named apatite by the German geologist Abraham Gottlob W…Effect of mechanical treatment on the mineralogical,,Jan 06, 2005· The scanning electron micrographs show that, on grinding, carbonate minerals are ground faster than apatite minerals. This means that at the same time of grinding, apatite grains are larger than carbonate ones ().Also, grinding of apatite minerals, particularly in the beginning, occurs along the length of the prismatic crystals more than crossing the crystals.

Apatite: The mineral apatite information and pictures

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.The extended Apatite supergroup describes additional minerals such as Pyromorphite, Mimetite, and,Effect of mechanical treatment on the mineralogical,,International Journal of Mineral Processing Volume 75, Issues 1–2 , 6 January 2005 , Pages 101-112 Effect of mechanical treatment on the mineralogical constituents of Abu-Tartour phosphate ore, EgyptApatite Gemstone Information at AJS Gems,Apatite displays strong fluorescence under short wave ultra-violet light. Apatite has a refractive index of 1.63 to 1.64 and a vitreous surface luster. The refractive index (RI), measured using a refractometer, is an indication of the amount light rays are bent by a mineral.
