| Popis: | New piezoelectric ceramics, (1− x )PbTiO 3 – x (Bi 1/2 ,Na 1/2 )(In 1/2 ,Nb 1/2 )O 3 with x =0.1, 0.2 and 0.3, were prepared using conventional ceramic processing. A single phase tetragonal perovskite was obtained for x =0.1 and 0.2. The piezoelectric and dielectric properties were compared, with the optimum properties of d 33 =56pC/N, k t =36%, k p =11% for the sample with x =0.2. The Curie temperature of the sample is about 446 °C. Dielectric loss is less than 5% for temperatures up to 400 °C, which made these ceramics suitable for piezoelectric devices operating at temperatures of 350 °C. |
