- W4382888803 abstract "Lead-free ferroelectric and piezoelectric ceramics, (Bi0.5Na0.5)TiO3 (BNT) ceramics doped with 1.0 wt % CuO (BNT + CuO) were prepared by the controlling the sintering temperature from 890 to 1140 °C. CuO is widely used as a sintering aid because of the formation of a liquid phase in various dielectric ceramics. In this study, we examined the electrical properties of BNT + CuO and discussed the low-temperature sintering mechanism. In addition, the role of CuO was clarified. As a result, the relative density of BNT + CuO sintered at 940 °C was 98 %. In addition, the electrical properties such as electromechanical coupling coefficient k33, piezoelectric constant d33, and depolarization temperature Td were 0.46, 75 pC/N, and 170 °C, respectively. These values are comparable to those of BNT ceramics sintered at 1140 °C, which is a typical sintering temperature. Therefore, the 1.0 wt % CuO addition enabled BNT ceramics to be sintered at an approximately 200 °C lower temperature. Moreover, to clarify the role of CuO, the compositions of BNT + CuO ceramics sintered at 940 °C were analyzed by scanning electron microscopy/energy-dispersive X-ray spectroscopy (SEM/EDS). A Cu-derived component was observed at the triple point of grains and these components contained Cu, Na, Ti, and O ions rather than Cu alone. That is, the melting point of CuO is lowered by its combination with Na and Ti ions and then the Na–Cu–Ti–O compound forms a liquid phase. Thus, by the addition of CuO, the formation of liquid-phase Na–Cu–Ti–O compounds led to sintering BNT ceramics at 200 °C lower temperature." @default.
