Solubility and diffusion of cobalt in alumina
Bibliographic record
Abstract
Abstract Diffusion of Co in alumina was carried out between 1403 and 1873 K in air with or without the presence of a spinel phase. The penetration profiles were obtained by the secondary-ion mass spectrometry (SIMS) technique and at the highest temperature by tracer measurement. The Arrhenius relation D(1403-1873K) = 6.2 × 109exp (-333kJmolminus;1) m2 sminus;1/RT describes the temperature dependence of the diffusion coefficient obtained by both methods. The formation of the spinel phase CoAl2O4 was observed when the experiments were carried out at temperatures lower than 1673 K. The formation of the spinel phase offered a good opportunity to calibrate the SIMS signal and the solubility of Co in alumina was found to be about (2–4) × 10minus;3 metal atom fraction in the temperature range 1403–1623 K.

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.
