Li2HfO3
Li2HfO3 is a stable, insulating lithium oxide ceramic frequently studied for its structural properties and potential roles in advanced materials science.
About Li2HfO3
Li2HfO3 is a thermodynamically stable lithium oxide that functions as a wide-gap insulating material. Its structural integrity and electronic properties make it a significant subject of study within the broader family of lithium-based ceramics.
Researchers value this compound for its stability, which is confirmed by its position on the convex hull. With numerous reported structures, it serves as an important model for understanding the behavior of lithium-containing oxides in various solid-state environments.
Key Properties
Cross-validated computational properties for Li2HfO3, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

A catalog of interpretation errors and compute failure modes from our materials discovery pipeline: thermostat overshoot (625K target / 750K actual), MACE artifacts on perovskites, PBE bandgaps presented without HSE correction, metallic DFPT results, phonon instabilities, 53 files with THz vs cm⁻¹ confusion, and more.
We tried four image-registry strategies to run Quantum ESPRESSO on Modal's serverless GPU infrastructure. apt_install hangs at tasks=0, ephemeral detach produces the same symptom, GHCR returns 403 Forbidden, and Docker Hub returns 'manifest not found.' The only viable path is a custom Dockerfile with QE compiled from source.
Every single Modal QE DFPT and HSE06 result from our April 2026 GPU compute campaign was an error payload, not usable data. 13 files landed on the volume with status ERROR, PSEUDO_ERROR, SCF_FAILED, DFPT_FAILED, PARSE_ERROR, or NOT_CONVERGED. The honest-null pattern in our ledger is what saved rankings from corruption.
How It Compares
Within the lithium oxides class.
Unlike the electrochemically active cathode materials in its class such as LiCoO2 or LiMn2O4, Li2HfO3 acts primarily as a stable insulator. It shares more structural commonalities with Li2TiO3, as both serve as robust, non-conductive lithium-based oxide frameworks rather than the transition-metal-heavy lithium oxides used for charge storage.
