| Abstract Scope |
Solid solutions type ((Ba0.5-x TiO3) La0.5+x) with x = 0, 0.01 and 0.02 were synthesized using the polymeric precursor method (Pechini). The influence of the La3+ dopant content on the structural parameters was determined. The X-ray results indicated the presence of the ferroelectric BaTiO3 doped La3+ phase. The Rietveld refinement results indicated the evolution of structural parameters, % wt phase obtained, crystallite size, microstructural stresses, space group, and cell volume obtained from BaTiO3 doped La3+. The Raman spectroscopy results showed the characteristic bands of the tetragonal ferroelectric phase around 300, 500, and 730 cm-1 respectively. The spectroscopy IR with Fourier transform results showed that no unwanted bonds were generated during the synthesis process. Therefore, could be established that the polymeric precursor method is effective for the synthesis of materials with a Perovskite type structure. |
