Hydroxyapatite (HA) use in biomedicine one as one of the promising biomaterials. Apatite-based
ceramics, derived from fine powder of calcinated bovine-bone (BHA), were successfully reinforced with
some materials like titanium, zirconia, lithium oxide, bio inert glass and yttria which contained
biocompatible elements, via sintering at different temperatures. In this study, hydroxyapatite (HA)
material, obtained from calcinated bovine bone (BHA), was mixed with 5 wt.% Al2O3-TiO2. In the Al2O3-
TiO2 compound, according to rate of the 3 wt.%, 8, 13, 20 and 40 for TiO2 has been changed. The pressed
samples were sintered at various sintering temperatures between 1000°C and 1300°C. Measurements of
compression strength, micro hardness, and density, and SEM observation were performed. Experimental
results showed that the samples with 13 wt.% TiO2 reached a maximum of densification and the highest
values of mechanical properties were achieved after sintering at 1300°C.
