| Popis: | Bi4− xEuxTi3O12 solid solution was synthesized by coprecipitation and characterized by X-ray powder diffraction, thermal analyses, Raman spectroscopy and scanning electron microscopy. Sintering temperature influence on microstructure is discussed in base of the scanning electron microscopy micrographs. Differential scanning calorimetric curves show a reversible phase transition around 665°C with an intensity changes as a function of the Eu3+ doping content. The transformation enthalpy has a maximum value for the undoped Bi4Ti3O12 samples and decreases with the increasing of Europium content. Finally, Raman studies of the samples show the vibrational changes induced by the Eu/Bi substituttion. |
