Densification behaviour and properties of manganese oxide doped Y-TZP ceramics
The effect of employing a short sintering holding time of 12 min as compared to that of the commonly employed holding time of 120 min (2h) on the properties of undoped and I wt manganese oxide (MnO(2))-doped Y-TZP ceramics were studied. Sintering studies was conducted over the temperature range of 1...
