Abstract

A powder mixture of 70 wt% Al₂O₃ and 30 wt% hydroxyapatite (HA) is sintered at 1300 °C or 1350 °C for 2 h at normal pressure. An MgF₂-added composition to make HA into fluorapatite (FA) is also prepared for comparison. The samples without MgF₂ show α & β-tricalcium phosphates (TCPs) and Al₂O₃ phases with no HA at either of the sintering temperatures. In the case of 1,350 °C, a CaAl4O7 phase is also found. Densification values are 69 and 78 %, and strengths are 156 and 104MPa for 1,300 and 1,350 °C, respectively. Because the decomposition of HA produces a H₂O vapor, fewer large pores of 5-6 βm form at 1,300 °C. The MgF₂-added samples show FA and Al₂O₃ phases with no TCP. Densification values are 79 and 87%, and strengths are 104 and 143 MPa for 1,300 and 1,350 °C, respectively. No large pores are observed, and the grain size of FA (1-2 μm) is bigger than that of TCP (0.7 μm ≥) in the samples without MgF₂. The resulting TCP/Al₂O₃ and FA/Al₂O₃ composites fabricated in situ exhibit strengths 6-10 times higher than monolithic TCP and HA.
