Tricalcium phosphate-zirconia composite ceramics were prepared. Mixtures of β-tricalcium phosphate and zirconia with 3 or 6mol% yttria were sintered in air at 1400°C. Phases of the β-tricalcium phosphate and zirconia almost remain unchanged after heating at 1400°C. The best material, composed of β-tricalcium phosphate and 67wt% zirconia with 6mol% yttria, has an average bending strength of 199MPa and fracture toughness value of 2.15MPa·m1/2.
