چکیده:

Hydroxyapatite nano powder synthesized via precipitation method. After characterizing the first powder using X-ray diffraction (XRD) and scanning electron microscope (SEM), HA-20 wt% titanium mixture waspressed and sintered in air, moist, and reduction atmospheres at 1200oC for 2 hr. Phase investigations of sintered bodies showed that HA-Ti nanocompo site is more stable in reduction atmosphere. But, in moist atmosphere hydroxyapatite completely decomposes to other phases. Also, decomposition of HA increases as a result of increasing temperature
