“…Table 1 shows properties of the TGG-LCCBT(parallel), TGG-LCCBT(perpendicular) and RO-LCCBT ceramics. The TGG-LCCBT ceramics were obtained by sintering specimens at 1,150°C for 10 h. The piezoelectric properties of the RO-LCCBT and RO-CBT ceramics have been investigated [24,25]. However, the RTGG-LCCBT(perpendicular) ceramics have a higher d 33 value compared with RO-LCCBT ceramics, which stems from arranged grains of textured ceramics.…”

“…The factors include sintering system, liquid additives [22] and the amount of the templates [23] and so on. Meanwhile, composition design has also been investigated to obtain better properties [24], as well as the morphological change. The addition of ''LiCe'' has been used to enhance the piezoelectric properties of CBT ceramics effectively in some reports [24,25].…”

The textured Ca 0.85 (LiCe) 0.075 Bi 4 Ti 4 O 15 (LCCBT) ceramics were fabricated by templated grain growth method, with the piezoelectric constant (d 33 ) around 29.5 pC/N. Owning to the orientation of the grains, the properties of the textured ceramics have been improved. The mechanism of texture development was explored for textured LCCBT ceramics. The factors contributing to the texture evolution include the templates growth, the morphological change of the matrix grains and the grains group formation. The change of the matrix grains goes through four stages: the equiaxed grains, the square tabular grains, the pyramid-like terraces, the platelike sheets.

“…However, the piezoelectric performance of pure NBT ceramics is quite weak; the value of piezoelectric coefficient d 33 is 16 pC/N [16]. Researchers have made many attempts, such as A- or B-site modification and grain orientation techniques, to overcome these shortcomings and improve the piezoelectric and ferroelectric properties of NBT ceramics [13,17,18]. In these studies, the B-site acceptor modification improved the piezoelectricity of NBT ceramics significantly [15].…”

This paper describes the design, fabrication, and characterization of tightly focused (ƒ-number close to 1) high frequency needle-type transducers based on lead-free Na0.5Bi4.5Ti3.975Co0.025O15 (NBT-Co) piezo-ceramics. The NBT-Co ceramics, are fabricated through solid-state reactions, have a piezoelectric coefficient d33 of 32 pC/N, and an electromechanical coupling factor kt of 35.3%. The high Curie temperature (670 °C) indicates a wide working temperature range. Characterization results show a center frequency of 70.4 MHz and a −6 dB bandwidth of 52.7%. Lateral resolution of 29.8 μm was achieved by scanning a 10 μm tungsten wire target, and axial resolution of 20.8 μm was calculated from the full width at half maximum (FWHM) of the pulse length of the echo. This lead-free ultrasonic transducer has potential applications in high resolution biological imaging.

“…It is well known that CeO 2 is commonly used as an effective additive in enhancing the piezoelectric properties of lead-based ceramics [9,11,12]. Therefore, we select CeO 2 as dopant to increase remnant polarization and decrease coercive electric field.…”

The composition of Sr 0.9 (Na 0.5 Bi 0.5 ) 0.1 -Bi 4 Ti 4 O 15 (SNBT) with excellent piezoelectric properties had been found recently. And basis on that, the effect of cerium modification SNBT-based ceramics was investigated in this paper. The Curie temperature and piezoelectric constant (d 33 ) for the 0.50 wt% cerium-modified SNBT-based ceramics were found to be 598°C and 27pC/N, respectively, which, together with the stable aging performance and thermal annealing properties, demonstrated that the cerium-modified SNBT-based materials are promising candidates for high-temperature applications.
