Effect of lead zirconate titanate on microstructure, mechanical and electrical properties of bismuth sodium lanthanum titanate ceramics
Ferroelectric ceramics with formula (Bi0.487Na0.487La0.017)TiO3/xPb(Zr0. 52Ti0.48)O3 (when x 0, 0.1, 0.5, 1.0 and 3.0 wt%) were prepared by solid-state mixed-oxide method and sintered at 1050 - 1200°C for 2 h. The optimum sintering temperature was 1100°C at which all samples had the density at least...

| الملخص: | Ferroelectric ceramics with formula (Bi0.487Na0.487La0.017)TiO3/xPb(Zr0. 52Ti0.48)O3 (when x 0, 0.1, 0.5, 1.0 and 3.0 wt%) were prepared by solid-state mixed-oxide method and sintered at 1050 - 1200°C for 2 h. The optimum sintering temperature was 1100°C at which all samples had the density at least 98% of theoretical values. X-ray diffraction results suggested that addition of PZT did not significantly affect unit cell of BNLT. An addition of PZT into BNLT effectively increased density and reduced grain size of the ceramics. These changes played an important role on mechanical properties improvement. Room temperature dielectric constant increased with increasing PZT concentration. The addition of PZT into BNLT slightly degraded ferroelectric properties, but improved the piezoelectric properties. © Published under licence by IOP Publishing Ltd. |
