In this research, low-voltage electromagnetic compaction (EMC) was applied to compact TiO 2 and PZT powders in the indirect way. After selecting the appropriate processing parameters, TiO 2 and PZT ceramics of higher density and better electrical properties were produced compared with traditional static compaction. The microstructures of two ceramics produced by two above-mentioned methods respectively show that, the average grain size of TiO 2 and PZT compacted by low-voltage EMC are about 8μm and 4μm which are smaller than that by static compaction respectively (15μm and 7μm) under the same sintered condition. Discharge voltage and charge capacitance are important factors to the green density and sintered part's density of each ceramics. Meanwhile, TiO 2 and PZT have their own discharge voltage range (700–1100V for TiO 2 and 600–1000V for PZT), during which each ceramic powder could be pressed effectively. With the same condition of charge capacitance, as the discharge voltage increases toward a peak value, the green density and sintered part's density increase, then tend to decrease after that peak value. The green density and sintered part's density of each ceramic increase and the above peak discharge voltage decrease slightly, as charge capacitance enlarges in the range investigated. In addition, effects of pancake coil turns and field shaper structure on the ceramic density were investigated. In most of cases investigated, the higher the ceramic part's density, the better the dielectric constants of TiO 2 parts and the piezoelectric constants of PZT parts.
