Phase developments and dielectric/ferroelectric responses in the PMN–PT system

Phase formation and dielectric properties of (Pb,Ba)[(Zn1/2W1/2),Ti]O3 ceramics

“…0.2). It was reported, however, that the anatase phase was not observed whenever second components of (Mg/Zn)(Ta/Nb) 2 O 6 were introduced to TiO 2 [7,[18][19][20]. Therefore, the survival of anatase (even at x < 1.0) in the present study seems to be related to the presence of W component.…”

Progress in synthesis of ferroelectric ceramic materials via high-energy mechanochemical technique

“…Combination of relaxor and relaxor is also an effective way to produce materials with desired electrical properties. Representative binary phases, such as PMN-PT [144][145][146][147][148], PZN-BT [153][154][155][156] and PMN-PFN [161], will be discussed to show the feasibility of high-energy mechanical activation in synthesizing ferroelectric materials. Three subsections, i.e.…”

“…(1 À x)PMN-xPT binary phases with different compositions demonstrate various dielectric, ferroelectric and piezoelectric properties [144][145][146]. 0.9PMN-0.1PT is a pronounced candidate to replace BT (BaTiO 3 ) in MLCs (multilayer ceramic capacitors) because it has lower sintering temperature as well as higher dielectric constant than BT.…”

Performance comparison of PZT and PMN–PT piezoceramics for vibration energy harvesting using standard or nonlinear approach

“…Another composition of interest is the PT-doped PMN, as such a ceramic is a relaxor-based ferroelectric with excellent electromechanical coupling. Compared to PZT, the piezoelectric coefficient of such materials can be increased by a factor up to 3 in lateral mode and exceed 2000 pC N −1 [12,13]. PT is interesting to use as dopant of PMN to adjust the Curie temperature (T C ) of the sample due to the fact that the polarization is disappearing over T C .…”
