High-Pressure Lattice Parameters for Iron-Doped Aluminum Oxyhydroxide

Lattice parameter measurements for the δ-(Al0.89Fe0.11)OOH material were collected at pressures from 2 to 65 GPa and temperatures from 300 to 800 K. The data, comprising 16.2 KB in an XLSX file, was generated by Chaoshuai Zhao using synchrotron single-crystal X-ray diffraction and published on figshare in 2026.

Use Cases

• Model the equation of state (EOS) of δ-(Al0.89Fe0.11)OOH using pressure and temperature as independent variables.
• Analyze lattice parameter evolution (e.g., a, b, c, α, β, γ, volume) across the 2-65 GPa and 300-800 K experimental range.
• Calibrate or validate computational models (e.g., DFT simulations) for iron-doped aluminum oxyhydroxides under high pressure-temperature conditions.
• Investigate the compressibility and thermal expansion behavior of the material by correlating lattice parameters with pressure and temperature data points.

Strengths

• Data covers a wide experimental range of 2-65 GPa and 300-800 K.
• Measurements were obtained using the authoritative synchrotron single-crystal X-ray diffraction method.
• Published under a permissive CC-BY-4.0 license for reuse.

Limitations

• The dataset is very small at 16.2 KB, indicating limited scope and likely a small number of data points.
• Data is specific to a single material composition (δ-(Al0.89Fe0.11)OOH), limiting generalizability.
• No column names or sample data are provided, complicating immediate analysis.
