Özet

In the present study, microstructural and mechanical properties of cerium oxide doped hydroxyapatite-alumina

composites were investigated by a series of tests. Six types of ternary composites with dissimilar rates of cerium

oxide (wt% 0.5-2.5) and alumina (wt% 2.5 and 5) were prepared, pelleted and sintered at various temperatures.

X-ray diffraction and scanning electron microscopy were used to evaluate phase changes and morphology of

sintered samples. Density, hardness and compressive strength measurements were used to determination of

mechanical properties. Experimental results show that the highest density and hardness were obtained to HA-

2.5A-2.5C samples as 3.11 gr/cm3 and 4.92 GPa, the highest compressive stength was obtained to HA-5A-2.5C

samples as 242 MPa.
