The influence of sintering conditions on the dielectric and piezoelectric properties of PbZrTiO–PbMgNbO ceramic tubes

Optimization of sintering temperature for the enhancement of pyroelectric properties of lead-free 0.88(Na0.5Bi0.5)TiO3–0.084(K0.5Bi0.5)TiO3–0.036BaTiO3 piezoelectric ceramics

“…The rotation of the domain with a large crystallite and grain size can be easily rotated compared to that of the smaller size [31,60]. These results correlate with the density variation of the sintering temperature results (Fig.…”

The effects of sintering temperatures on dielectric, ferroelectric and electric field-induced strain of lead-free Bi0.5(Na0.78K0.22)0.5TiO3 piezoelectric ceramics synthesized by the sol–gel technique

“…However, at a sintering temperature of 1150 C, the dielectric curve exhibits a clear T d position, indicating that the sample is well crystallized at a sintering temperature of 1150 C. The maximum dielectric constant increased significantly with an increased sintering temperature from 1075 to 1150 C. This is because the grain size increases with the increase in sintering temperature, however the number of grain boundaries decrease, leading to the reduction of space charges [17,22]. The high dielectric constant at a sintering temperature of 1150 C can be attributed to the high density, larger grain size and improvement in crystalline quality [17,23]. There are many reports describing the dependence of the dielectric constant on grain size [24e26].…”

“…The debinding temperature of last stage was determined considering the Pb loss in the PMN-PZT ceramic. Based on previous research by Xue et al [22] and Han et al [23], final stage of debinding is determined as well below the temperature of Pb loss. Figure 14 shows the surface of sintered rectangular specimen with respect to the debinding rates.…”
