“…The values of the dielectric loss at T c (tanδ c ) are listed in Table . As the sintering temperature increased up to 1400 °C, the increase in the dielectric constant may be caused by the grain size becoming much larger, leading to a decrease in the number of grain boundaries, contributing to the higher density seen in Figure and reducing the dielectric loss values . The degeneration of the dielectric properties in BCTS ceramics with higher sintering temperatures was caused by porous structures forming at the grain boundaries which caused a high electrical conductivity, as was observed in the SEM photographs.…”

“…Generally, the transition of phases in perovskite structures with changing sintering temperatures can be attributed to many factors such as homogeneity of materials, reactivity of starting powders, and processing variables . Moreover, the increased sintering temperatures can increase the diffusion of elements within the structural regions and lead to a relative homogeneous local composition in the material which causes it to form the actual crystal structure . In this work, the multi O + T + R phases were formed only at the sintering temperature of 1400 °C, which assumed that the energy at a sintering temperature of 1400 °C was sufficient to induce the homogeneity in the local composition of BCTS ceramics.…”

“…Lead vacancies reduce the stress level in the crystalline lattice and allow internal movements in the lattice. Therefore, these effects increase the piezoelectric performance [23]. Portelles et al [24] have reported very large dielectric permittivity values in the vicinity of the transition temperature.…”

“…It has been observed that the properties of these ceramics are very sensitive to the composition fluctuation near the MPB, sintering temperature and dopant concentration. In order to achieve a high degree of molecular mixing, chemical homogeneity, control of stoichiometry, low calcination and sintering temperature, various chemical methods [12] have been used for the synthesis of these compounds. However, processing of PZT ceramics by a solid-solution mixing process has the advantages of convenient preparation and low cost [13].…”
