Composition‐induced non‐ergodic–ergodic transition and electrocaloric evolution in Pb1−1.5x Lax Zr0.8 Ti0.2 O3 relaxor ferroelectric ceramics

IET Nanodielectrics, Volume 2, Issue 4, Page 123-128, December 2019., 2019
Relaxor ferroelectrics, with polar nanoregions (PNRs), are good candidates for electrocaloric (EC) refrigeration. This study investigates the EC performance of the Pb1−1.5x Lax Zr0.8 Ti0.2 O3 relaxor ferroelectric ceramics by the direct measurement using a modified differential scanning calorimeter. All the ceramics exhibit pure perovskite phase with a

Homogeneity of Large-scale PLZT Ceramics

Journal of the Japan Society of Powder and Powder Metallurgy, 1977
Optical transmittance, grain size and ferroelectric properties are measured along the radial direction of large-scale (40-50 mmφ) PLZT-7.6/70/30 ceramics in order to evaluate the homogeneity in a plate. Ferro-antiferroelectric transition temperatures (Th) are measured by the pyroelectric method.
