- Abstract
- Piezoelectric 0.93(Na0.5K0.5)NbO3-0.07BiTiO(3) (NKN-BTO) ceramics were fabricated by the mixed-oxide method and their structural and dielectric properties was investigated with the variation of sintering temperature. All specimens were crystallized in the perovskite single phase without any formation of a second phase such as pyrochlore. The average grain size of the NKN-BTO specimen sintered at 1130 degrees C is 0.32 mu m. The specimen sintered at 1100 degrees C showed the highest relative density of 98%. Electromechanical coupling factor, relative dielectric constant and dielectric loss of the NICN-BTO specimens sintered at 1110 degrees C were 0.31, 1222 and 0.02, respectively. Curie temperature of the specimen sintered at 1110 degrees C was 445 degrees C.
