Y[2]O[3]-doped tetragonal-ZrO[2] ([ss])/α-Al[2]O[3] dense ceramics were composed of 280-130 nm grains. FE-SEM observation revealed that their microstructures, that is the grain sizes of both t-ZrO[2]([ss]) and α-Al[2]O[3], and the distribution of α-Al[2]O[3] grains, were much influenced by the content of α-Al[2]O[3]. The best mechanical properties of extreme high bending strength (σ[b] ≥ 1 GPa) and high fracture toughness ([K][IC] ≥ 15 MPa·m[1/2]) were attained simultaneously at the composition of 25 mol%
