Sintering Behavior and Microstructure Character of Magnesia Partially Stabilized Zirconia Ceramics

摘要

Commercial magnesia partially stabilized zirconia (MgO-PSZ) has been selected as the starting materials. Different sintering temperatures have been investigated to determine the optimal conditions. The sintering behavior and characteristic of MgO-PSZ are investigated in this work. Microstructures have been obviously affected by different sintering temperature. According to dilatometer curve, sintering curve and the shrinkage ratio of sintering process have been estimated. The obtained microstructures have been characterized by scanning electron microscope (SEM).
