Abstract

The aim of this study was to prepare the ceria-stabilized zirconia (Ce-TZP)/alumina nanocomposite powder suitable for the electrophoretic deposition (EPD) in the fabrication of dental restorations. The mixtures of Ce-TZP and γ- Al2O3 powder were calcined at 1200, 1300, or 1400 °C and were ball-milled in a wet and dry condition. Then, EPD was performed and the weight of the deposited material was determined. In case of the specimens calcined at 1300 and 1400 °C composite particles were observed with a transmission electron microscope. However, no composite particles were found in the specimens prepared at 1200 °C. The maximum deposit weight was 115.2 mg/cm2 (1200 °C), followed by 70.0 mg/cm (1300 °C), and 66.6 mg/cm2 (1400 °C). The deposit weight tended to decrease as the calcination temperature increased and the particle size became larger.
