In this study, firstly hydroxyapatite powder using natural method and bovine bone was synthesized at temperature of 900 ° C. Then it was synthesized reproducibiliby from foam ceramic scaffolds with 0, 3, 6 and 9 wt% and 50 wt% titania hydroxyapatite wet grinding method (slurry). In order to detect the changes of phase and chemical bonds was used diffraction of X-rays and infrared light spectroscopy. Microstructure and morphology of the nano composites was examined by scanning electron microscopy. According to the results, the volume fraction of porosities were obtained about 80-85%. The compressive strength was measured 0.14 to 1.321 MPa .Results indicate that the best type of scaffold physical properties such as porosity and shrinkage after sintering about low percentages of titanium dioxide, the 3 and mechanical properties suitable, the high percentage of titanium dioxide is the 6 percent.
