摘要：

Hydroxyapatite is a particularly attractive material for human tissue implantation. The intrinsic poor mechanical properties of hydroxyapatite material can lead to instability and unsatisfactory duration of the implant in the presence of body fluids and local loading. Addition of TiO2 in the hydroxyapatite matrix can enhance the mechanical properties of the obtained composite. The composite with 15 % TiO2 content shows a thermal stability of the system and improved mechanical properties.
