On the feasibility of synthesizing complex perovskite ferroelectric ceramics via a B-site oxide mixing route

Preparation and electrical properties of (1−x)Sr(Fe1/2Nb1/2)O3–xPbTiO3 ferroelectric ceramics

“…Above dielectric behavior can be attributed to the existence of iron ions and often appears in the iron-containing lossy ferroelectrics [4,7,10,[12][13][14].…”

“…Stoichiometric SrCO3, PbO and TiO2 were added to the synthesized wolframite precursor after carefully grinding, and the mixed powders were calcined at 1050 • C for 4 h. XRD measurement confirmed that the calcined powders are of pure perovskite phase. The calcined powders were then dry-pressed into pellts with the addition of 1 wt% polyvinyl alcohol (PVA) binder and sintered at 1150 • C for 2.5 h. The pellets were buried under an equiweight mixed raw oxides with the same composition in a covered crucible to minimize the volatilization of lead during sintering [10].…”

Structure and Electrical Properties of Oxide Doped Rhombohedral Pb(Ni1/3Nb2/3)O3-PbTiO3 Ferroelectric Ceramics

“…For electrical property measurement, silver paste was coated on both surfaces of the well-polished pellets and fired at 550℃ for 30 min to provide robust electrodes. Detailed phase structure characterization, micromorphology observation and electrical properties measurement procedures were described elsewhere [7][8].…”

“…0 0 / the perovskite structure, electrical properties and MPB effects of the PNN-PT system. By the way, special efforts should be undertaken on ceramic processing and sintering profile for the preparation of the lead-containing ferroelectric ceramics in order to suppress the evaporation of lead during sintering [7]. O 6 , and the well-mixed powders were calcined at 900℃ for 2 h. The calcined powders were then drypressed into pellets with the addition of 1 wt% polyvinyl alcohol (PVA) binder and sintered at different temperatures.…”

Ferroelectric phase transition and optical performance of PLZnNZT transparent ceramics

“…Ceramics are advantageous material form, since their physical properties can be tailored easily via composition change and ceramic processing improvement to meet the requirements of various applications [6]. Therefore, for the multicomponent system, appropriate modification by doping heterovalent ions and formation of solid solutions deserve special research interest, which can increase ceramic densification, decrease compositional disorder and defect concentration, and improve microstructural homogenization and isotropy [7][8][9].…”
