“…Moreover, the lattice parameter values obtained by this method presented small variations compared to those reported in the literature [11,[60][61][62][63][64]. These differences can be related to the preparation method, synthesis conditions (heat treatment temperature, time), lattice distortion, residual stresses in the lattice and/or structural defects.…”

“…This behavior can be ascribed to change of crystal structure as already discussed in Ref. [20]. XRD data reveal that BiFeO 3 was obtained by the soft chemistry method with rhombohedral distorted perovskite structure.…”

“…In terms of ceramics, although several studies have been carried out to investigate the effects of lanthanum addition on various properties of BIT ceramics, their starting materials were produced by chemical or high-energy milling routes [3,6,8,9]. These previous studies also focused only on the properties of Bi 3.25 La 0.75 Ti 3 O 12 which has been reported to be the best composition in BLT system [10,11].…”

Effect of concentration of La doping on phase, microstructure and properties of 0, 0.25, 0.5, 0.75, 1) ceramics was investigated. X-ray diffraction patterns of the ceramics indicated orthorhombic structure with lattice distortion, especially with higher content of La dopant. All samples showed plate-like morphology with different grain size and orientation. Preferred orientation in undoped and lightly doped BLT ceramics was dominant compared to the samples with high La contents. The reduced preferred orientation in highly doped BLT was accompanied by a decrease in grain size and a slight decrease in density. The temperature dependence of dielectric constant showed a decrease in T c with increasing La concentration. Dielectric constant measured at room temperature tended to increase with La-content. An addition of La also improved mechanical characteristics of the BIT ceramics.
