Hydroxyapatite(HAp)-zirconia composite ceramics were prepared by simplified synthesis process and then their properties were investigated. Composite powders of HAp and zirconia were successively synthesized under Ca/P=1.69, 1.71, 1.73 and pH=11 by precipitation method. HAp-zirconia ceramics were obtained with sintering of these various HAp-zirconia composite powders. These sintered bodies were mainly composed of HAp and ZrO2(tetragonal), but it was found that a little of HAp was decomposed into TCP as the amount of zirconia and the sintering temperature were increased. When HAp having 10~15wt.% ZrO2 content were sintered in the range of 1150 to 130$0^{circ}C$, the apparent porosity was about 7~11%. This showed that the successive synthesis process employed here had a limit to obtian more densified composite ceramics.
