Titanium incorporated hydroxyapatite preparation was endeavored using TiH2. Titanium has good mechanical properties, good biocompatibility and bioactivity. Titanium incorporated hydroxyapatite material prepared for orthopedic applications were reported to be better mechanical properties. Hydroxyapatite (HAp) was synthesized by wet chemical facile method and after calcination was mixed with TiH2 (5 to 20%).The effect of sintering on phase formation, microstructure, density and porosity of Hap/TiH2was studied by sintering at temperatures from 900°C to 1200°C. The properties of the samples were characterized using X-ray diffraction technique (XRD), Scanning electron microscopy(SEM), Fourier transform spectroscopy (FT-IR), density and porosity. The results from studies showed the presence of β-tricalcium phosphate (β-TCP) and perovskite (CaTiO3) as the major crystalline phases; while minor reaction products like α-TCP and TTCP were also recorded for samples with higher amount of TiH2irrespective of sintering temperatures. Morphology evaluation by SEM revealed the presence of CaTiO3needle structure at temperature till 1000°C, above which it appeared hexagonal due to crystal growth. Functional groups, density and porosity were also studied.

Titanium reinforced hydroxyapatite preparation was attempted by using TiH2. The hydroxyapatite (HAp) was obtained from wet chemical facile method and was mixed with TiH2 (5 to 20 wt.%). The mixtures were shaped by pressing and samples were sintered at different temperatures from 900 to 1200?C. X-ray diffraction results showed that all the high temperature sintered samples with higher amount of TiH2 contain ?-tricalcium phosphate (?-TCP) and perovskite CaTiO3 as the major crystalline phases, while minor reaction products like ?-TCP and tetracalcium phosphate (TTCP) were also recorded for the various HAp-TiH2 composites. Microstructure evaluation was done by scanning electronmicroscopy which revealed the change in microstructure from needle-like to hexagonal grainy structure with increasing TiH2 content. Fourier transform infrared spectroscopy was done for functional groups analysis while density and porosity were also measured to analyse sintering ability of the composite samples.
