Electrical properties of (1-x)BCZT-xBZT lead-free ceramics
The aim of this study was to investigate the electrical properties of (1-x)[Ba0.85Ca0.15Zr0.1Ti0.9]O 3 - x[(BiZn0.5Ti0.5)O3] ceramics system for x = 0.00 - 0.10.

| Summary: | The aim of this study was to investigate the electrical properties of (1-x)[Ba0.85Ca0.15Zr0.1Ti0.9]O 3 - x[(BiZn0.5Ti0.5)O3] ceramics system for x = 0.00 - 0.10. The (1-x)BCZT-xBZT ceramics were fabricated via solid state reaction technique. The samples were calcined and sintered at 925°C for 6 h and 1370°C for 3 h, respectively. Phase formation and microstructure of (1-x)BCZT-xBZT ceramics were studied using an X-ray diffractometer (XRD) and scanning electron microscope (SEM). The physical properties and electrical properties, such as dielectric properties and ferroelectric properties were examined. It was found that all the samples show pure perovskite phase. The BZT content lead to the change and improved of the dielectric properties of ceramic samples. The dielectric loss values were lower than 0.01 (at 1 kHz) for all samples. The samples show higher degree of the relaxor like behavior with higher BZT content. In addition, the ferroelectric properties were found to depend on the BZT content. © 2013 IEEE. |
