AB  - Promena strukture i osobina biokompozitnog materijala HAp/PLLA tokom mehano­hemijskog tretmana predmet su analize u ovom radu.

AB  - Mechanochemically treated hydroxyapatite/poly-L-lactide (HAp/PLLA) composite biomaterial undergoes significant changes in structure and properties. These were the subject of the analysis presented in this paper. HAp/PLLA mixture was evaporated in vacuum and then subjected to dry milling in a planetary ball mill for 480 minutes. Characterization of the material obtained was carried out using X-ray diffraction (XRD), differential scanning calorimetry (DSC), scanning electronic microscopy (SEM), transmission electronic microscopy (TEM) and infrared spectroscopy (IR). These techniques confirmed that mechanochemical treatment induces changes in the composite biomaterial. The most significant changes are reduction of PLLA crystallinity and size of HAp crystalites. Homogeneous phase arrangenment is obtained by extending the duration of mechanochemical treatment.

AB  - Powder mixture of Ca(OH)(2)-P2O5-CaF2 were milled in planetary ball mill. A carbonated fluorhydroxyapatite, FHA Ca-10(PO4)(1-y)(CO3)(y)(PO4)(5)(OH)(2-2x1)(F)(2x1) was formed after 5 h of milling and carbonated fluoroapatite Ca-10(PO4)(1-y)(CO3)(y)(PO4)(5)(F)(2) was formed after 9 h of milling. Complete transformation of the carbonated form of FA into then single phase of FA occurred after 9 h milling and thermally treating. The various experimental techniques like X-ray Diffraction (XRD), Differential Thermal Analysis (DTA), Infrared Spectroscopy (IR), Transmission Electron Microscopy and Scanning Electron Microscopy (SEM) were used to characterize the synthesized powders and to postulate reaction mechanisms steps- transformations of reactants involved.
