Abstract

Titanium-hydroxyapatite (Ti-HA) composites were obtained by sintering 95 wt% titanium and 5 wt% hydroxyapatite type calcium phosphates powder prepared by sol-gel method. X-ray diffraction (XRD) and infrared analysis confirm the development of HA type crystalites in the sol-gel samples. Ti and HA powders were pressed without the use of any lubricant. The bioactivity of composite Ti-HA was tested in simulatated body fluid. Biologically active hydroxyapatite similar to the mineralised bone tissue was developed in vitro under in vivo simulated conditions. Raman spectroscopy and XRD data evidence the development on composite surface of hydroxyapatite type phase after (simulated body fluid) soaking..
