| heal.abstract | Biologically derived hydroxyapatite from calcinated (at 850 degrees C) bovine bones (BHA) was doped with 5 wt% and 10 wt% of SiO(2), MgO, Al(2)O(3) and ZrO(2) (stabilized with 8% Y(2)O(3)). The aim was to improve the sintering ability and the mechanical properties (compression strength and hardness) of the resultant BHA-composites. Cylindrical samples were sintered at several temperatures between 1,000 and 1,300 degrees C for 4 h in air. The experimental results showed that sintering generally occurs at 1,200 degrees C. The BHA-MgO composites showed the best sintering performance. In the BHA-SiO(2) composites, extended formation of glassy phase occurred at 1,300 degrees C, resulting in structural degradation of the resultant samples. No sound reinforcement was achieved in the case of doping with Al(2)O(3) and zirconia probably due to the big gap between the optimum sintering temperatures of BHA and these two oxides. | en |
