| Abstract: | Hydroxyapatite (HA)-YTZP (2, 5, 7.5, and 10 wt% ZrO2) composite powders prepared from inorganic precursors were characterized by FTIR, DSC/TG, XRD, and TEM. The calcined powders had HA and t/c-ZrO2, which undergo structural changes between 650°C and 1050°C. TEM of calcined powder showed larger HA particles (100 nm) and smaller ZrO2 particles (≤50 nm). HA and HA-2 wt% ZrO2-sintered samples had 98% density and it was (90-95%) for HA-5, 7.5, and 10 wt% ZrO2. The bending strength of HA-2wt% ZrO2 composites was 72 MPa. The grain sizes of HA showed a refinement with ZrO2 addition. |
