| Abstract Scope |
The synthesis and electrical characterization of compositions based on Nb5+ doped BaTiO3 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 hours and acetone as a control agent. The resulting powders were carried out a complete decarbonation at 1000 ºC for 5 hours, followed by a double sintering from 1100 ºC to 1500 ºC. The sintered powders were characterized by Raman, XRD and SEM; pellets were formed by uniaxial cold-compacted and were sintered at high temperature, then characterized by XRD, SEM and electrical properties. In XRD x= 0.005 a doublet can be seen at ≈45º, for x= 0.04 the double peak is observed at ≈55º, which indicates the tetragonal distortion of the cubic cell. |
