| 概要 |
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 degrees Celsius and were ball-milled in a wet and dry condition. Then, electrophoretic deposition (EPD) was performed and the weight of the deposited material was determined. In case of the specimens calcined at 1300 or 1400 degrees Celsius, composite particles were observed with a transmission electron microscope. However, no composite particles were found in the specimens prepared at 1200 degrees Celsius. The deposit weight tended to decrease as the calcination temperature increased and the particle size became larger. Based on results of this study, it is possible to produce the nanocomposite powder that can be used for EPD by the use of Ce-TZP and γ-Al2O3. |
