Enhanced Electrocaloric Effect in Lead Zirconate Titanate Ceramic Wafer
https://orcid.org/http://orcid.org/0000-0001-9802-3478
The present study reports application of lead zirconate titanate (PZT) wafer, prepared by tape casting route, for enhanced electrocaloric effect, measured as a function of temperature in the temperature range 313-495 K. Polarization versus electric field (P–E) hysteresis loop was traced at different temperatures. The electrocaloric response, as manifested by adiabatic temperature change (ΔT), was estimated indirectly by employing Maxwell’s thermodynamic equations. The maximum electrocaloric strength, ΔT/ΔE ~ 1.37 KmV−1, has been attained, at T = 450 K, for ΔT = 1.74 K under the electric field 12.5 kV/cm. The electrocaloric response and electrocaloric strength obtained from the tape cast PZT wafer are larger than its bulk ceramic counterpart reported in the published literature.
