STRUCTURAL CHARACTERIZATION OF Bi<sub>6</sub>Ti<sub>3</sub>Fe<sub>2</sub>O<sub>18</sub> OBTAINED BY MOLTEN SALT SYNTHESIS
Bibliographic record
Abstract
Magnetoelectric Aurivillius phase Bi6Ti3Fe2O18 is obtained by molten salts synthesis (MSS). A description of the experimental conditions for preparing the compound is given. Scanning electron microscopy observation reveals that obtained crystallites show plate-like shape, with small size dispersion. MSS allows efficient control of crystallites' size. The crystal structure of the investigated phase is analyzed at the Stanford synchrotron powder diffractometer. Results of Rietveld structure analysis are given. Space group is F2mm. Cell parameters (in Á) are: a = 5.4967(2), b = 5.4655(2), c = 49.342(1). Iron ions tend to concentrate in perovskite octahedra far from the bismuth oxide layers.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
