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

Phase structure and electrical properties of 0.8Pb(Mg1/3Nb2/3)O3–0.2PbTiO3 relaxor ferroelectric ceramics prepared by the reaction‐sintering method

“…The well‐mixed powders were dry pressed into pellets 12 mm in diameter and 2 mm in thickness with the addition of an appropriate amount of polyvinyl alcohol (PVA) binder. The pellets were sintered in a temperature range of 1180–1270 °C for 2 h with a binder burning step at 550 °C for 2 h. During the sintering process, the pellets were buried under an equiweight powder with the same composition in a closed alumina crucible to minimize the evaporation of lead during sintering 9.…”

“…For piezoelectric property measurement, the ceramics were poled under an electric field of 2 kV/mm at 120 °C for 15 min in silicone oil and then slowly cooled to room temperature while maintaining half‐magnitude of the applied electric field, which is sufficient to make the FE ceramics fully poled. Detailed electrical properties measurement procedures were described elsewhere 9.…”

Study of structural, dielectric and electrical behavior of (1−x)Ba(Fe0.5Nb0.5)O3–xSrTiO3 ceramics

“…Unlike normal BaTiO 3 , the high permittivity materials are considered necessary for temperature stable multilayer capacitors, to show abnormally flat dielectric temperature curves [16]. Several researchers [17][18][19][20][21][22][23] had reported that the BFN-based electroceramics exhibit a very attractive dielectric and electric properties over a wide range of temperatures. Considerable debates still exit concerning the physical mechanisms governing their dielectric and electrical behaviours [19].…”

Structural, Optical and Improved Electrical Properties of Relaxor‐Based Single Crystals After Poling

“…Piezoelectric property was measured by a ZJ‐6A Berlincourt‐type quasi‐static d 33 / d 31 meter. Detailed other electrical properties measurement procedures were described elsewhere …”

“…Detailed other electrical properties measurement procedures were described elsewhere. 15,16 Figure 1 shows XRPD pattern of the PMN-0.305PT crystal powder. Due to the segregation during the crystal growth and the feature of complex perovskite solid solution, composition variation will inevitably occur in the as-grown single crystals.…”
