Effects of MnO2 doping on the electrical properties of BCZT ceramics prepared by seed-induced method

บทคัดย่อ ( Abstract )

The effects of MnO2 doping on the electrical properties of Ba0.85Ca0.15Ti0.9Zr0.1O3 (BCZT) ceramics prepared by adding 1.0 mol% BCZT seed were studied Results were found that the ceramics showed pure perovskite phase phase for all samples. Density and grain size values were in the range of 5.45–5.57 g/cm3 and 6.79–9.85 lm, respectively. The highest values of er and Pr measured at room temperatures were 3900 and 8.22 lC/cm2, respectively which were obtained for the sample of 1.0mol% MnO2. Tan d of all ceramic samples was lower than 0.02. In addition, d33 and g33 values were changed with MnO2 content.
