“…As an example, piezoelectric properties of relaxor-PT single crystals poled along different crystallographic directions can be significantly different, and many of these crystal cut and poling configurations can be unique in many applications [25,[28][29][30][31][32][33][34][35][36]. In the matter of crystal growth methods, various growth techniques including high temperature solution, Bridgman, and solid state conversion methods have been developed and reported [37][38][39][40]. Relaxor-PT single crystals with different compositions grown by different growth methods were characterized considering their poling directions and crystal groups.…”

Relaxor-PbTiO 3 piezoelectric single crystals have been widely used in a broad range of electromechanical devices, including piezoelectric sensors, actuators, and transducers. This paper reviews the unique properties of these single crystals for piezoelectric sensors. Design, fabrication and characterization of various relaxor-PT single crystal piezoelectric sensors and their applications are presented and compared with their piezoelectric ceramic counterparts. Newly applicable fields and future trends of relaxor-PT sensors are also suggested in this review paper.

“…Accordingly, we can notice that the amount of Zr and Sn in the crystals increased a little with that of Ti decreased. A noticeable segregation of Ti component can be observed, as found in many PT-containing ferroelectric crystals [18,19] due to the strong affinity between Ti 4+ and O 2-ions. Figure 3 shows the XRD patterns of the calcined powders and the ground PLZST crystal powders.…”

Relaxor antiferroelectric single crystals lead lanthanum zirconate stannate titanate (PLZST) with the composition around the morphotropic phase boundary (MPB) have been grown by flux method using 50 wt% PbO-PbF 2 -B 2 O 3 as a flux. The obtained crystals are light yellow in color. The XRD patterns revealed that the habitual faces of the obtained crystal are (001). The crystal morphology was studied and related to a layer growth mechanism controlled by two-dimensional growth. The chemical composition of as-grown crystal was analyzed by inductively coupled plasma atomic emission spectrometry (ICP), indicating a slight decrease of the amount of Ti compared to the starting materials. The result was verified by the XRD patterns with the phase transformation from the co-existence of tetragonal and rhombohedra phases to the single tetragonal phase.

“…Relaxor-based ferroelectric single crystals (1-x)Pb(Mg 1/ 3 Nb 2/3 )O 3 -xPbTiO 3 (PMN-xPT) have been widely studied in recent years because of their superior piezoelectric coefficients (d 33 [ 2000 pC/N) and electromechanical coupling factors (k 33 [ 0.90) with compositions near the morphotropic phase boundary (MPB, x * 0.33) [1,2], which makes them the promising candidates for applications such as ultrasonic transducers [3,4], actuators [5] and pyroelectric devices [6]. Unfortunately, the relatively low Curie temperature (T C * 140°C) and rhombohedral (R) to tetragonal (T) phase transition temperature (T R-T * 80°C) of PMN-PT render the single crystals unfavorable for high temperature applications [7].…”

Ternary ferroelectric single crystal Pb(In 1/2 Nb 1/ 2 )O 3 -Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PIN-PMN-PT) was grown by the modified Bridgman method. The compositional variation of different regions of the crystals was measured, and the segregation regularity of the crystals was proposed. Variations in the dielectric properties and domain structures of the PIN-PMN-PT single crystals were investigated as a function of temperature and composition, and the phase transformation behavior of the crystals was observed. The PIN-PMN-PT crystals showed high Curie temperatures (T C = 160-210°C), ferroelectric phase transition temperatures (T R-T up to 132°C) and coercive fields (E C = 6-8 kV/cm) as well as excellent piezoelectric properties (d 33 up to 2,800 pC/N) and electromechanical coefficients (k 33 [ 0.90). As the temperature increased, k 33 values remained relatively constant and d 33 increased gradually prior to ferroelectric phase transformation, and these results reflect the wide temperature usage range of PIN-PMN-PT single crystals. The polarization (P r ) and E C of the crystals showed unique trends during the phase transformation process; high P r and E C values can be maintained prior to depolarization, which indicates that the PIN-PMN-PT single crystals are candidate materials for high-power applications. In summary, PIN-PMN-PT single crystals with ultrahigh electric properties, large coercive fields and excellent thermal stability may potentially be applied in harsh environments.
