Abstract Scope |
The present investigation studied the synthesis and microstructural characterization of Niobium and lanthanum-doped BaTiO3 (BT) synthesized by the Pechini method. 4 samples of BaTiO3 with 0, 1, 2, 3 & 6 wt.% of Nb5+ and La3+ were synthesized. The microstructural analysis and determination of the evolution of BaTiO3 structural parameters as a function of dopant content was performed by X-ray diffraction (XRD) and Rietveld refinement. The analysis of the effect of doping on the structural morphology and particle size, as well as the elemental distribution of the dopants, was performed by High-Resolution Scanning Electron Microscopy (HR-SEM). Additionally, thermogravimetric analysis (TGA) was performed to determine the evolution of the properties of the samples as a function of dopant content and temperature. The results obtained allowed us to establish the solubility limit of the dopant ions in the perovskite-type structure. |
