Effect of Mn doping on structure, the dielectric and electric properties of BCZT ceramics

The synthesis of (Ba 0.99 Ca 0.01 )(Zr 0.2 Ti 0.8 )O 3 (BCZT) and doped (Ba 0.99 Ca 0.01 )(Zr 0.2 Ti 0.8-x Mn x )O 3 (BCZT-xMn) ceramics was successfully carried out by the solid-state method. The doping effect is followed by X-ray powder diffraction, scanning electron microscopy (SEM), and dielectric and conductivity measurements. Indeed, X-ray diffraction measurements show the crystalline structure of ceramics. SEM images indicate the doping effect on the studied perovskite microstructure. The results indicate that during doping the maximum value of the temperature (Tm) of the dielectric constant varies slightly, and there will be a considerable decrease in permittivity, dielectric losses and conductivity. Manganese ions are well integrated in the perovskite while maintaining the solid solution.
