ABSTRACT

3Y-TZP block doped with HfO2 and CeO2 for dental ceramic block to the proliferation of CAD/CAM systems was prepared by heating at 800~1100℃ and then sintering at 1450℃. The influences of heating temperature and addition of HfO2 and CeO2 on the mechanical and chemical properties of 3Y-TZP block were investigated. Using the EDS mapping images, HfO2 and CeO2 was well dispersed in the 3Y-TZP matrix. 3 wt% HfO2 doped block showed the optimum biaxial strength (1 GPa), while 3 wt% CeO2 doped block enhanced the stability of t-ZrO2 under hydrothermal atmosphere.
