They were sintered at 1573 to 1623 K (1300~1350°C) for 6.0×10^2 s (10 min) under 50 MPa in Ar. Thus-obtained ceramics consisted of 130~150 nm grains, composed of α-Al_2O_3 and tetragonal-ZrO_2 with a small amount of monoclinic-ZrO_2. Dense ceramics with high relative densities ≥99.5% revealed high mechanical properties: bending strength (σ_b) higher than 1.3 GPa and simultaneous fracture toughness (K_IC) higher than 15.5 MPa·m^1/2, which value was evaluated by the indentation fracture toughness (IF) test. X-ray diffraction (XRD) analysis, SEM and TEM with EDS observations on the as-prepared and calcined powders, and the microstructures of ceramics demonstrated the homogeneous grain distribution of t-ZrO_2 and α-Al_2O_3, with the former grains being surrounded by the latter which had segregated from the calcined cubic ZrO_2 solid solution containing both Al_2O_3 and
