The effect of employing a short sintering holding time of 12min as compared to that of the commonly employed holding time of 120min (2h) on the properties of undoped and 1wt% manganese oxide (MnO 2 )-doped Y-TZP ceramics were studied. Sintering studies was conducted over the temperature range of 1150–1600°C. Bulk density, Young's modulus, Vickers hardness and fracture toughness tests were...
The sinterability of yttria-tetragonal zirconia polycrystals (Y-TZP) containing small amounts of MnO 2 as sintering aid was investigated over the temperature range of 1250–1500°C. Sintered samples were evaluated to determine bulk density, Young's modulus, Vickers hardness and fracture toughness. In addition, the tetragonal phase stability of selected samples was evaluated by subjecting the...
