Abstract Scope |
BaTiO3 is a ceramic compound of ABO3 perovsakite type where Ba occupies the A site and Ti the B site. The saturation of the BaTiO3 lattice with Eu3+ allows the formation of secondary phases with specific applications. In this work, the Eu2TiO5 phase was synthesized using solid state reaction method and sintering at 1300°C for 6 hours through the Ba1-xEuxTi1-x/4O3 electronic compensation mechanism with x=0, 10 and 15 by Weight % of Eu+3. The X-ray diffraction spectra of the analyzed samples indicate the presence of the crystalline phase Eu2TiO5 (JCPDS 96-200-2716). Rietvel refinement analysis of the orthorhombic Eu2TiO5 structure indicated an increase in the lattice parameters ¨a¨, ¨b¨ and ¨c¨ and in the cell-volume attributed to the increase in Eu+3 concentration. Additionally, the presence of Eu2TiO5 was verified by Raman spectroscopy studies in the band at 778cm-1. The Eu2TiO5 phase find electrical, optical, magnetic and nuclear applications. |
