摘要

The synthesisSynthesis and electrical characterizationCharacterization of compositions based on Nb5+-doped BaTiO3BaTiO3 was carried out using the Ba1−x/2Ti1−xNbxO3 mechanism, and x = 0.001, 0.003, 0.005, 0.04, 0.08, 0.20, and 0.25 Nb5+ by the solid-state reaction. Compositions were prepared with BaCO3 + TiO2 + Nb2O5 and were ground in PET containers with zirconia balls for 5 h and acetone as a control agent. The resulting powders were carried out a complete decarbonation at 1000 °C for 5 h, followed by a double sinteringSintering from 1100 to 1500 °C. The sintered powders were characterized by Raman, XRDX-Ray Diffraction (XRD), and SEMScanning Electron Microscopy (SEM); pellets were formed by uniaxial cold-compacted and were sintered at high temperatureTemperature, then characterized by XRDX-Ray Diffraction (XRD), SEMScanning Electron Microscopy (SEM), and electrical propertiesProperties. In XRDX-Ray Diffraction (XRD) x = 0.005 a doublet can be seen at ≈ 45°, for x = 0.04 the double peak is observed at ≈ 55°, which indicates the tetragonal distortion of the cubicCubic cell.
