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 gamma- Al(2)O(3) powder were calcined at 1200, 1300, or 1400 degrees 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 degrees C composite particles were observed with a transmission electron microscope. However, no composite particles were found in the specimens prepared at 1200 degrees C. The maximum deposit weight was 115.2 mg/cm(2) (1200 degrees C), followed by 70.0 mg/cm(2) (1300 degrees C), and 66.6 mg/cm(2) (1400 degrees C). The deposit weight tended to decrease as the calcination temperature increased and the particle size became larger.
