摘要：

In this paper, the influence of different sintering temperatures on the microstructure, density, shrinkage and final phase content of hydroxyapatite-zirconia (HA-ZrO2) composites was studied. Composites of hydroxyapatite with 3 mol% Y2O3 stabilized zirconia with MgO were sintered between 1100 degrees C and 1400 degrees C. The reaction and the transformation of phases were investigated by X-ray diffraction and FTIR spectroscopic measurements. Those results indicated that the processes of HA dehydroxylation were found, the mean grain size of the sample sintered was varied from 1.2 mu m to 5.3 mu m. Dimension shrinkage increased to 0.24% as the sintered temperature increased from 1100 degrees C to 1400 degrees C, the bulk density increased monotonically to 95.6% with increasing temperature up to 1400 degrees C.
