“…The two Figures, 3(a, b) and 4(a, b) give the experimental results, the measurements of the dielectric parameters including the dielectric constant (εr) and the dissipation factor (tanδ) of the PLNZNCT ceramic sintered at 1200 °C, at the frequency of 1kHz depending on the temperature. According to previous studies, the doping of the acceptor ions in the perovskite crystal lattice decreases the dielectric constant and increases the curie temperature (Tc) [14]. The strongest dielectric response is that associated with the doped sample of 1mol %Cr.…”

The purpose of this work is to show the effect of Chromium (Cr) on the microstructural and dielectric properties of solid solution: [Pb(0.975) La0, 015Nd0.01][(Zr0, 524Ti0, 476) (0.9875-(w/4))Nb0.005 CrwO3] with w = 0.0, 0.5, 1.0, 2.5 and 5.0 molar % (abbreviated PLNZNCT) were developed by solid state chemical reaction. The analysis by X-ray diffraction and the calculation of the tolerance factor (t) show a stable single-phase perovskite structure of tetragonal symmetry sintered at 1200°C. The SEM micrograph, the density test and the dielectric measurements indicate that the PLNZNCT ceramic achieves optimal values at 1 mol% Cr3 +. These obtained results, perhaps characterize the classic hard ferroelectric materials.

This paper describes solid solutions in the quasibinary oxide system iridium-titanium IrO 2 À TiO 2 with rutile and anatase crystal structures. Based on X-ray diffraction evaluations using Rietveld refinements, changes of lattice parameters were determined within the composition series of 0-100 mol % iridium. These changes prove the existence of a complete solid solution series in the rutile structure type. The solubility limit for iridium in the anatase lattice was found to be 6.0(8) mol % iridium for the underlying sol-gel process. In addition, iridium is a promoter for the conversion from anatase to rutile type. Furthermore, the Xray diffraction results of a calcination temperature series for the composition with 5 mol % iridium are shown, which confirm the findings of the composition series and allow conclusions on the phase segregation behavior. The results are complemented by 2-point conductivity measurements at different pressures in a piston press to investigate the question of the conductivity mechanism.
