Abstract Scope |
Barium titanate is an ABO3 type perovskite, of great interest due to its magnetic, dielectric, piezoelectric, and thermal properties, among others. At room temperature BaTiO3 presents a stable tetragonal crystalline structure. In this work, solid solutions of the Ba1-3xGd2xTi1-3xEu4xO3 type were sintered by the solid state reaction method in air at 1300°C for 6 hours with steps of 4°C per minute with x = 0, 0.001, 0.002 and 0.003 percentage. in weigh. The tetragonal (JCPDS 96-150-7757) and cubic (JCPDS 96-155-9964) phase of BaTiO3 was determined by x-ray diffraction and Rietveld refinement. The evolution of the equilibrium of the phases was analyzed according to the increase of the dopants Eu+3 and Gd+3 and the increase in the stability of the cubic phase of BaTiO3 was determined, the decrease of the capacitance values when increasing the dopants agree with the stability of the cubic phase. |
