Coupled Experimental and Thermodynamic Optimization of the Na <sub>2</sub> O–FeO–Fe <sub>2</sub> O <sub>3</sub> –Al <sub>2</sub> O <sub>3</sub> System: Part 1. Phase Diagram Experiments
Bibliographic record
Abstract
As part of the complete thermodynamic modeling of the Na 2 O–FeO–Fe 2 O 3 –Al 2 O 3 system, the Na 2 O–FeO–Fe 2 O 3 –Al 2 O 3 phase diagrams in air (1583 and 1698 K) and at Fe saturation (1573 and 1673 K) were investigated using the quenching method followed by Electron Probe Micro‐Analyzer ( EPMA ) and X‐ray Diffraction ( XRD ) phase analysis. General features of the phase diagrams in this system were well revealed for the first time. A complete meta‐oxide solid solution between NaAlO 2 and NaFeO 2 was observed. An extensive solid solution of Na 2 (Al,Fe) 12 O 19 Na‐βˮ‐alumina was found and the existence of a miscibility gap in this solution was confirmed. Several compatibility triangles of three‐phase assemblages were also identified in air and at Fe saturation.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
