“…However, this hypothesis seems unlikely, as the final density of the undoped samples is higher than the final density of the doped samples and the main mass loss occurs after densification is almost completed. 20 However, considering the coefficients of Al 2 O 3 and SiO 2 in Eq. (3) (0.02 vs 0.08) leads to the assumption that the Al 2 O 3 is not completely dissolved in the liquid phase.…”

Lead zirconate titanate (PZT) ceramics are used in a wide range of applications as sensors and actuators. Typically, they are formulated by the mixed oxide route, using several mixing and milling steps. Due to wear, these processes introduce impurities into the ceramic mass, which on their part can strongly influence densification behaviour and final properties of the PZT. In this study, the effect of such impurities, such as iron oxide, alumina, and silica, on the sintering behaviour and microstructure development of PZT ceramic is evaluated. A commercial Nb‐doped PZT powder was used and doped by adding Al2O3, SiO2, and Fe2O3 with an amount of up to 0.001 mol%. Bulk samples were prepared and sintered in air. The mass loss, density, and grain size were correlated by regression analysis using the doping elements and levels, respectively. Due to the complex interactions between the oxides and the ceramic properties, the experiments were performed with the design‐of‐experiment method (DoE). The results showed a significant influence of these low amounts of doping levels on the microstructure development. Moreover, it was shown that doping after calcination affects the microstructure in a similar way to doping before calcination. Thus, a possibility to compensate concentration variations in the calcined ceramic mass is demonstrated, to homogenize the chemical composition and the final microstructure of the sintered PZT ceramic in the manufacturing processes.

“…Concurrently, sintering aids support the densification progress of the PZT particles. 3 could have a similar effect as CuO. This piezoelectric properties increasing effect could be related to the semiconductive nature of CuO [12] and WO 3 [13].…”

“…For multilayered stacks the inner electrodes have to be co-fired with the ceramic. The electrical connection of PZT in multilayer devices is mostly realized by expensive high-temperature resistant metals, as Pt [2] or Ag/Pd [3]. The usage of cost-effective Ag-electrodes is hampered by the high sintering temperature of PZT, which is about 1200 °C.…”

“…They exhibit a much larger electro-optical effect than LiNbO 3 [6] and [7], which is commonly used in commercial waveguide devices. The incorporation of lanthanum into the lattice enhances the densification rates of the PZT ceramic, leading to pore-free homogeneous microstructures [8] and also the lanthanum radius is comparable with Pb that can be substituted at A-site [3]. The contribution of La 3+ ion in PZT has enhanced its domain wall mobility.…”

Ferroelectric materials of lanthanum (La) doped PbZrTiO3 (PLZT) were investigated via first principles study. The structural, electronic and optical properties of PLZT in tetragonal structure (P4mm space group) were performed in the framework of density functional theory (DFT) with generalized gradient approximation (GGA) and local density approximation (LDA) methods. The calculated results of structural properties of PLZT were seen to be approximately close to the experimental data. The results of the electronic part were covered with the calculation of energy band gap and density of states (DOS). The highest valence band (VB) which lies at the Fermi level (EF) was dominated by the O 2p at F point. The conduction band (CB) of PLZT occurred at G point, which was primarily dominated by Ti 3d mixed at Pb and La p-state. Whereas the optical part was covered with the refractive index and absorption. The refractive index, n and the extinction coefficient, k were calculated with respect to photon energy. Those results obtained could be such a good prediction in studying parameters and properties of new materials.
