A curated experimental and physics-constrained benchmark dataset for doped zirconia ionic conductivity

This dataset contains a three-layer data resource for doped zirconia ionic conductivity: the source Excel workbook sample_data.xlsx, 1,351 curated experimental reference records, a normalised composition-processing-property relational schema, and a frozen physics-constrained synthetic benchmark with 1,025,619 raw synthetic material-sample records and 1,025,612 compliant synthetic material-sample records. The files are organised as linked tables for material samples, dopants, sintering steps, crystal phases and dictionaries, with source-level provenance, validation outputs, downstream machine-learning validation results, figure source data, a manifest and SHA-256 checksums. The synthetic records are intended as a fixed benchmark for model testing and synthetic-data validation, not as replacements for experimental measurements.
