| Abstract Scope |
The structural evolution of solid solutions BaTiO3-type doped with La3+ and Bi 3+ was investigated. The samples were prepared according to the formula Ba1-3xLa2xTi1-3xBi4xO3 for the compositions x = 0.0, 0.001, 0.0015, and 0.002 of La3+ and Bi 3+ (wt. %) and were synthesized by the ball milling method. Then, the powder mixture was sintered with a thermal ramp of 4°C/min for 5 hours and maintained at 1200°C for 5 more hours. The structural properties of synthesized doped BaTiO3 were characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The analysis of XRD patterns revealed the presence of tetragonal BaTiO3(96-150-7757) and allowed to calculate the lattice parameters (a, c) for each composition. The volume of the unit cell decreased for the x>0.0 compositions in comparison to pure BaTiO3 which can be attributed to the addition of the ions La3+ and Bi 3+ in the BaTiO3 structure. |
