Thermodynamic modeling of the CoO–SiO<sub>2</sub> and CoO–FeO–Fe<sub>2</sub>O<sub>3</sub>–SiO<sub>2</sub> systems
Bibliographic record
Abstract
Abstract A complete critical evaluation and thermodynamic modeling of the phase diagrams and thermodynamic properties of oxide phases in the CoO – FeO – Fe 2 O 3 – SiO 2 system at 1 bar total pressure are presented. Optimized equations for the thermodynamic properties of all phases were obtained which reproduce all available thermodynamic and phase equilibrium data within the limits of absolute experimental accuracy from 25 °C to above the liquidus temperatures at all compositions and oxygen partial pressures. The database of the model parameters can be used, along with software for Gibbs energy minimization, to calculate any type of phase diagram section. Unexplored phase diagram sections and activities of CoO, FeO and SiO 2 in this system of industrial importance are predicted from the thermodynamic models with the optimized parameters.

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; a candidate call from one teacher head, not a consensus.
