TOWARDS A SAFETY ENVIROMENT: HOW APATITE MINERALS REMEDIATE Pb, Zn and Mn FROM WASTE WATER? [PDF]

open access: yesJournal of Soil Sciences and Agricultural Engineering, 2010
To evaluate the effectiveness of apatite minerals in removing different contaminants, from low quality water in the industrial city of abha, Asir region, southwestern of Saudi Arabia, two phosphatic clay dominated by apatite mineral were selected.

APATITE OF ALKALINE ROCKS OF THE VISHNEVOGORSKY COMPLEX, SOUTH URALS [PDF]

open access: yesМинералогия, 2019
Apatite Ca5(PO4)3(F,Cl,OH) is a widespread accessory mineral of alkaline rocks of the Vishnevye Mountains in the Urals. There are small bodies of carbonatites and micaceous rocks, where apatite is a rock-forming mineral.

Apatite formation on electrochemically modified surface of hafnium metal in simulated body environment

open access: yesJournal of Asian Ceramic Societies, 2022
Biomedical application of Hf for hard tissue repair may be expanded if it can be imparted with bone-bonding ability. Apatite formation in the body is required for artificial materials to bond to bone. We have shown that apatite can form on NaOH- and heat-

Mineralization Behavior of the Petal-Like Apatite/TiO2 Composite Coating Prepared by Micro-Arc Oxidation

open access: yesInternational Journal of Electrochemical Science, 2012
The mineralization behavior of the petal-like apatite/TiO2coating, which was prepared by micro-arc oxidation (MAO) on the surface of the commercially pure titanium, was studied in simulated body fluid (SBF).

Characterization of a calcium phospho-silicated apatite with iron oxide inclusions [PDF]

open access: yes, 2011
An iron oxide containing calcium phosphate–silicate hydroxyapatite was synthesized by calcination at 900 °C of a sample obtained by precipitation in basic aqueous solution of Ca, P, Si, Fe and Mg containing acidic solution made from dissolution of ...

U–Pb Dating, Gemology, and Chemical Composition of Apatite from Dara-e-Pech, Afghanistan

open access: yesCrystals, 2023
Minerals of the apatite group commonly occur in granite pegmatites, and their ability to incorporate a wide range of trace elements makes them a good indicator of magma composition and magmatic–hydrothermal processes.

Triclinic apatites

open access: yesActa Crystallographica Section B Structural Science, 2007
Apatites commonly adopt P63/m hexagonal symmetry. More rarely, monoclinic chemical analogues have been recognized, including the biologically significant hydroxyapatite, Ca10(PO4)6(OH)2, but the driving force towards lower symmetry has not been systematically examined.

α-tricalcium phosphate/fluorapatite-based cement - promising dental root canal filling material [PDF]

open access: yesProcessing and Application of Ceramics, 2022
α-Tricalcium phosphate/fluorapatite (α-TCP/FAp) mixed powders were prepared in order to obtain dental root canal filling cements. Different liquids for cement pastes have been investigated and the most suitable one for obtaining rheologically optimal ...

Production, by co-grinding in a media mill, of porous biodegradable polylactic acid-apatite composite materials for bone tissue engineering [PDF]

open access: yes, 2009
This paper presents the results of a study of the production of porous biodegradable composite materials by co-grinding, followed by scaffolding. Dry powders of polylactic acid and nanocrystalline carbonated apatite, analogous to bone mineral were co ...
