The role of dopants in the samples was studied in terms of phase stability, microstructures, and mechanical properties. Accordingly, 0.5, 1, 3, and 5�wt% manganese were doped into yttria-stabilized zirconia and heated at temperatures ranging from 1300��C to 1550��C. The study revealed that the milling process reduced powder particle size from 0.54�?m to 0.16�?m. The grain size of the samples increased with increasing sintering temperature, and adding manganese dopants promoted further grain growth. When sintered at 1450��C, 3�wt% manganese enhanced the densification of the sample to a relative density of 95.8% and Vickers hardness peaked at 14.4�GPa. The samples with manganese dopants exhibited fracture toughness values of 4.1�4.6�MPa���m1/2 when sintered at temperatures above 1450��C, regardless of dopant content. Zircon was found on the surface of the sintered sample with over 3�wt% manganese addition but did not disrupt zirconia phase stability. The study showed that the mechanical properties of yttria-stabilized zirconia improved when manganese dopants were added. � 2016 Elsevier Inc.
