Abstract
This paper presents the study of the effect of sintering temperature on microstructure and mechanical strength of zirconia sintered part prepared using powder metallurgy process. Three different sintering cycles were applied to the zirconia compacted powder during the sintering process. The results showed that sintering temperature asserts influence in the formation of interparticle bonding in the sintered parts. Examination of the polished surface indicated that higher sintering temperature results in stronger interactions between the particles. Therefore the sintered parts prepared under higher sintering temperature (1500℃) achieved greater strength compared to the sintered parts prepared under 1300℃ operating temperature.
