Abstract
Hydroxyapatite [Ca10(PO4)6(OH)2] powder was sintered with addition of aluminumisoproxide (C9H21AlO3) 4 wt % and various wt % of titanium fluoride TiF4. The prepared pellets were sintered at 1250°C temperature. The various wt % of TiF4 were used for fluoridation and densification of hydroxyapatite. For studying the phase compositions, microstructure and elemental analysis, the sintered specimens were characterized by X-ray diffraction XRD, Scanning electron microscopy SEM, and energy dispersive electron spectroscopy EDAX respectively. After sintering highest relative density was found to be 96.42 % with Vickers hardness and bending strength 1.22–1.62 GPa and 13.39–35.88 MPa respectively. As a result of sintering fluoridated apatite composite material was obtained.
