Barium titanate (BaTiO3) doped with Eu3+ was synthesized by the Solid State Reaction method. The milling of BaCO3, TiO2 and Eu2O3 was carried out in an agate mortar with acetone as a control medium for 25 minutes and compositions of x = 0.001, 0.007, 0.05 and 0.1 % by weight of Eu3+. The precursor powders TiO2, BaCO3 and Eu2O3 were mixed and calcined at 800 ° C for 8 hours and sintered at 1200 ° C for 5 hours. X-ray difracction results revealed the predominant ferroelectric tetragonal BaTiO3 phase for low compositions, and secondary phases (Eu2TiO5) for mixtures with high concentrations of Eu3+. The X-ray mapping images showed a uniform distribution of Ti, Ba and Eu in the samples. The incorporation of Eu3+ ions into the BaTiO3 system could greatly manifest dielectric properties and can find immense scope in electronic elements including ceramic capacitors.
