摘 要：In the current work hydroxyapatite Ca10(PO4)6 ·OH2(HA) was sintered with the addition of 3 wt% aluminum isopropoxide(C9H21AlO3) powder and 3 wt % Teflon powder(-C2 F2-). Sample was prepared by following sol-gel technique. Obtained pellets of samples were sintered. For investigation of effects of temperature on microstructures and mechanical properties the samples were sintered at various temperatures. For studying the phase composition, microstructures and elemental analysis the sintered samples were characterized by X-rays diffraction(XRD), scanning electron microscopy(SEM) and energy dispersive X-rays diffraction(EDAX) respectively. After sintering the samples mechanical properties, i e, grains size, apparent density, Vickers hardness, bending strength and compressive strength were found to be 2.14-18.76 μm, 1.523 6-0.752 g/cm3, 3.60-0.600 GPa and bending strength 33.265 8-14.900 MPa, 75-33 MPa, respectively. As a result of sintering fluoridated composite material was obtained.
