| 英文摘要 | Enhanced electrical resistivity about over two orders of magnitude for Na0.5Bi2.5Nb2O9 (NBNO) high-temperature piezoceramics potentially used in piezoelectric sensors is achieved by the introduction of highly insulating Al2O3 addition. Possible pyrochlore secondary phases of two types of grains: irregular polyhedral and platelike, forming at the grain boundaries, have significant blocking effect on the electric current paths and thus lead to improved electrical resistivity. Al2O3-modified NBNO ceramics show higher d(33) values up to 16.5 pC/N than that of pure NBNO ceramics (12.4 pC/N) because higher electric field is applied during poling process owing to enhanced electrical resistivity, whereas the T-c values keep almost constant. A compromise between high T-c, good polarizability and enhanced electrical resistivity has been achieved by suitable addition of Al2O3, which would shed light on how to obtain novel Aurivillius phase ferroelectrics for practical applications at high temperature. |
