Study of physical and mechanical properties of BG/HA/TiO2 biocomposite for bone implantation.

In the present study composition of HA, TiO2 and bioglass were successfully synthesized and biocomposites were prepared by powder metallurgy method. Microstructure and morphology of the biocomposites were examined by scanning electron microscopy (SEM). Analytical, thermal and microstructural investigations were carried out by XRD, SEM, DTA/TGA techniques, and results shows considerable higher rates of apatite formations. The dissolution behavior of the bioactive glasses and biocomposites in SBF showed in vitro test for all samples. Addition of X%HA and X%TiO2 in (100-2X%) 45S5 bioglass improves mechanical properties such as hardness, compressive strength, elastic modulus of these biocomposites.
