“…The brazing temperatures of joining piezoelectric ceramic materials [1,2] and shape memory alloys [3,4] which are always above the transition temperature range of materials could result in the magnetic transformation and degradation of properties. To avoid deterioration of these basic metals and to achieve strong resultant joints, much more efforts have been contributed to develop affordable solder/filler metal with suitable melting temperatures [5,6].…”

“…The piezoelectric constant (d 33 ) was measured using a quasistatic piezo d 33 meter (model ZJ-3AN; Institute of Acoustics, Chinese Academy of Sciences, Beijing, China). The electromechanical coupling coefficient (K p ) and electromechanical quality factor (Q m ) were determined using the resonance-antiresonance technique 16,17 through an impedance analyzer. The dielectric properties were measured at frequency of 1 kHz using an LCR analyzer (HP 4192; Hewlett Packard Ltd., Palo Alto, CA).…”

0.35Pb(Ni 1/3 Nb 2/3 )O 3 -0.65Pb(Zr 0.41 Ti 0.59 )O 3 (PNN-PZT) ceramics doped with 0.5PbO-0.5B 2 O 3 glass have been synthesized by the conventional solid-state sintering technique. The effects of 0.5PbO-0.5B 2 O 3 glass on the sintering temperature and piezoelectric properties of PNN-PZT ceramics were studied. The results indicated that the sintering temperature of PNN-PZT was significantly reduced due to the incorporation of 0.5PbO-0.5B 2 O 3 glass dopant. When the content of 0.5PbO-0.5B 2 O 3 glass was 0.5 wt.%, the sintering temperature of PNN-PZT was observed to reduce from above 1200°C to 920°C while the samples maintained high density (7.91 g/cm 3 ), excellent piezoelectric constant (d 33 = 479 pC/N), large electromechanical coupling coefficient (K p = 0.55), and relatively low electromechanical quality factor (Q m = 79). Moreover, large dielectric constant (e 33 T /e 0 = 2904) and low dielectric loss (tan d = 0.0166) were obtained in this work.

“…Despite their robust properties, Pb-based materials face notable global restrictions, hence why it is necessary to develop new environment-friendly materials. Barium titanate BaTiO3 (BT) is a typical alternative system that can become an important candidate for this application [5]- [7].…”

Structural, dielectric, ferroelectric, energy storage properties, and electrocaloric effect were studied in lead-free ceramic Ba0.95Ca0.05Ti0.89Sn0.11O3 (BCTSn) elaborated by sol-gel method.Phase purity structure was confirmed from X-ray data using Rietveld refinement analysis which revealed the coexistence of tetragonal (P4mm) and orthorhombic (Amm2) symmetries at room temperature. Phase transitions were detected by dielectric and differential scanning calorimetry results. Energy storage properties were determined from P-E hysteresis, and the electrocaloric properties were calculated indirectly via the Maxwell approach. The large value of electrocaloric temperature change of ΔT=0.807 K obtained at a relatively small field of 30 kV cm -1 and high energy storage efficiency can make BCTSn ceramic a promising candidate for environmentally friendly refrigeration and energy storage applications.
