Summary: The influence of solid content on the pore morphology and mechanical and piezoelectric properties of porous BCZT ceramics was systematically investigated. The results showed that an increase in solid content led to a decrease in porosity and pore size, an increase in ceramic connectivity, and an increase in compressive strength. The best ferroelectric performance was achieved at a solid content of 30%, while the relative dielectric constant and piezoelectric constant increased with an increase in solid content. At a solid content of 20%, the maximum values of g33 and FOM33 were obtained.

Summary: This study investigates the influence of BMT on the microstructure, dielectric properties, and energy storage performance of relaxor ceramics. With the increasing content of BMT, the grain size of the ceramics gradually increases, the dielectric constant decreases, and a high energy storage performance is achieved at x = 0.15.

Summary: The microstructure, dielectric properties, relaxor behavior, and energy storage efficiency of un-substituted and niobium (Nb) substituted (Ba-0.85 Ca-0.15)(Zr-0.1 Ti-0.9) (1-x) NbxO3 samples prepared by the solid-state reaction method were studied. The addition of niobium was found to inhibit grain growth and induce structural and phase changes. The Nb substituted samples exhibited relaxor behavior and higher energy storage efficiency, making them promising materials for energy storage applications.

Summary: In this study, high-dielectric (1 - x)(Bi0.5Na0.5)TiO3-x(Ba0.85Ca0.15)(Zr0.1Ti0.9)O-3 (BNT-BCZT) ceramics were fabricated by combining solid-state sintering technique and two-part synthesis. XRD measurements confirmed the formation of a stable solid solution between BNT and BCZT. The BNT-BCZT ceramics exhibited larger piezoelectric constant, lower remnant polarization, and lower coercive field compared to pure BNT ceramics.

Summary: By introducing SLT and lithium carbonate as additives to BCZT ceramics, the energy storage performance can be improved. SLT can improve energy storage efficiency, while lithium carbonate can reduce sintering temperature and promote grain densification. With the appropriate concentration of additives, the energy storage density and efficiency of BCZT ceramics can be increased.

Summary: The energy-harvesting ability of the lead-free ferroelectric Ba(Zr,Ti)O-3 was investigated and greatly enhanced using the Kim novel electrothermodynamic cycle for low-temperature application. The synthesized Ba(Zr,Ti)O-3 material with a Zr:Ti ratio of 10:90 exhibited a mix relaxor-ferroelectric behavior. The highest energy density achieved in a practical test for this lead-free ferroelectric bulk material in the BaTiO3 family was 504 mJ/cm(3).

Summary: Barium calcium zirconate titanate (BCZT) and sodium bismuth titanate (NBT) are important lead-free ferroelectrics with excellent electrical properties. In this study, Ce-BCZT and NBT ceramics were synthesized and their phases, morphologies, electrical and mechanical properties were analyzed. It was found that the addition of NBT to Ce-BCZT ceramics increases the Curie temperature and decreases the elastic modulus. Composition with x = 0.75 (NBT75) has potential for use in ultrasonic cleaners.
