It contains comprehensive characterisation data for ferroelectric lead zirconate titanate PZT NCE51 ceramic, fabricated using both freeze-casting and conventional solid state route. This dataset contains hysteresis polarisation-electric field loops, impedance spectroscopy data and X-ray diffraction (XRD) patterns, which provide insights into how the microstructure of freeze-cast samples affect the functional properties of the porous freeze-cast ceramics. In addition, the dataset also contains the results of finite element model, demonstrating how the local field distribution differ between the structures produced via freeze-casting and the burnt-out polymer spheres (BURPS) technique, despite having the same relative density. This difference demonstrate how the permittivity measured differ between these microstructures. The dataset supports further analysis of the processing-microstructure-property relationships in porous ferroelectric ceramics. This may be of interest to researchers working on design and characterisation of advanced ferroelectric composites. 2025-11-10 University of Bath public RightsHolder University of Bath Mrs Bui Thi Thanh Nga Engineering and Physical Sciences Research Council https://doi.org/10.13039/501100000266 EP/V011332/1 New Investigator award - Microstructural engineering of piezoelectric composites UK Research and Innovation https://doi.org/10.13039/100014013 EP/X023265/1 Frontier Research Guarantee - Processing of Smart Porous Electro-Ceramic Transducers (ProSPECT) cent_imps Full details of the methodology can be found in Section 2 of the associate research article. https://doi.org/10.1088/1361-6463/ae1d88 en 1 10.15125/BATH-01332 https://doi.org/10.1088/1361-6463/ae1d88 pub open An additional data file is available in version 2 of this dataset.
