The effects of sintering additives on the sintering of 3Y-TZP ceramic

The influence of 0.5 wt.% of manganese oxide (MnO2) addition as dopant into 3 mol% yttria stabilized tetragonal zirconia polycrystals (3Y-TZP) were studied in comparison to undoped 3Y-TZP using different sintering profiles. Samples were sintered at 1200 degrees C, 1300 degrees C and 1400 degrees C w...
