Dielectric, ferroelectric, and energy storage efficiency of (Ba0.85Ca0.15)Zr0.1Ti0.9O3/BaTiO3 and Ba0.7Ca0.3TiO3/BaZr0.2Ti0.8O3 bilayer ceramic
The Ba0.85Ca0.15Zr0.1Ti0.9O3/BaTiO3 and Ba0.7Ca0.3TiO3/BaZr0.2Ti0.8O3 bilayer ceramics are fabricated via a solid-state sintering method. The phase, microstructure, and chemical composition of the bilayer ceramics are compared with pure ceramics, i.e., BaTiO3 (BT), Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT), Ba0.7Ca0.3TiO3 (BCT), and BaZr0.2Ti0.8O3 (BZT). The crystal structure of both bilayer ceramics did not differ from that of each pure ceramic. The bilayer structure has a good interface bonding between each layer. The bilayer ceramics have two-phase transition temperatures, which come from BCZT and BT for the BCZT/BT system and BCT and BZT for the BCT/BZT system. Compared with pure ceramic, the interface causes a decrease in εm of the bilayer ceramics. The difference between the maximum polarization and remanent polarization (ΔP) has an essential role in improving the energy storage efficiency of these ceramics. The results suggest modification in the ceramic's dielectric and energy storage efficiency by bilayer structure.
