Abstract

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 with holding time of 1 min, 12 min, 2 hours and 20 hours all for single step sintering. The optimal sintering profiles are A4 and C2 where 3Y-TZP doped with 0.5% wt. MnO2 sintered at 1400 degrees C for 12 minutes and 1200 degrees C for 20 hours respectively. At these sintering parameters, the MnO2 doped 3Y-TZP sample exhibited relative density of similar to 97%, Vicker's Hardness value of similar to 13 GPa, Fracture toughness value of similar to 4 MPam1/2 and Young's modulus of similar to 210 GPa.
