Abstract

Zirconia ceramic doped with 9.7% mole MgO was synthesized by solid state method at 1300°C to 1500°C for 1 hour to 6 hours following a factorial experimental design. XRD analysis of sintered samples showed that the phases formed were dependent on sintering temperature. SEM and SMA results revealed microcracks and surface uplift in samples containing single monoclinic ZrO₂ phase. The grain size was observed to be dependent on sintering temperature and ZrO₂ phases formed. The hardness obtained by indentation method was found to be lower for samples sintered at 1300°C and 1400°C than for samples sintered at 1500°C due to the lower density contributed by microcracks in monoclinic ZrO₂.
