| Abstract Scope |
BaTiO3 is generally made by reacting BaCO3 with TiO2 at a temperature of about 1100 °C. The current trend is to produce powders with a strict control of purity, Ba/Ti ratio and particle size, which affects the generation of reproducible microstructures and constant dielectric properties in the sintered product. In this work, the synthesis of solid solutions of BaTiO3 doped with Eu3+ was carried out and they were synthesized by the solid-state reaction method. The concentration was varied from x= 0, 0.003, 0.05 and 0.10% by weight of Eu3+. The powders were decarbonated at 900 °C and sintered at 1300 °C for 5 hours. The experimental results obtained by X-ray diffraction show the consolidation of tetragonal BaTiO3 and the Raman spectroscopy shows the corresponding BaTiO3 spectra that confirm the consolidation in the sintering process. The scanning electron microscopy results mainly showed particles with necks characteristic of the sintering process. |
