Influence of fluoride addition on hydroxyapatite prepared for medical applications

الملخص EN

In this study, hydroxyapatite (HAP, Ca10 (PO4) 6 (OH) 2) has been prepared as bioceramic material with biological specifications useful to used for orthopedic and dental implant applications.

Wet chemical processing seems to form the fine grain size and uniform characteristic nanocrystalline materials by the interstice factors controlling which affected the grain size and crystallinity in order to give good mechanical and / or constituent properties similar as natural bone.

Fluorinated hydroxyapatite [4-6 wt % F, (FHA, Ca10 (PO4)6(OH) 2–Fx] was developed in new method for its posses to increased strength and to give higher corrosion resistance in biofluids than pure HAP moreover reduces the risk of dental caries.

The phase's and functional groups characterizations XRD & FTIR reveled the purity of the product and its free of other phases, while the morphology tests showed the compound homogeneity as fluoride interpenetrated in the compound lattice net.
