| Abstract Scope |
In this study, the synthesis of Er3+ and Cr3+ co-doped BaTiO3 was carried out using the Ba1-3xCr2xTi1-3xEr4xO3 mechanism, with x = 0, 0.1, and 0.15 using the method of mechanical grinding method employing zirconia balls of three different diameter sizes (2.95 mm, 5.05 mm, and 6.48 mm) for 6 h and dried and acetone as a control agent. The resulting powders were sintered at 1200°C for 6 h using a heating rate of 4°C/min. The structural evolution of the obtained samples was monitoring by X-ray Diffraction (XRD), Rietveld refinement analysis and Scanning Electron Microscopy (SEM-EDS). The XRD patterns revealed the formation of ferroelectric tetragonal phase BaTiO3 doped with Er3+ and Cr3+ and significant changes in the structural parameters for the doped samples compared to undoped BaTiO3 were determined. SEM-EDS results showed a homogeneous distribution of the sintered particles and the formation of necks between particles characteristic of the sintering process. |
