Cesium Oxo-fluoro-aluminates in the CsF–Al<sub>2</sub>O<sub>3</sub> System: Synthesis and Structural Characterization
Bibliographic record
Abstract
In an experiment combining various approaches, a precise examination of a portion of the phase diagram of a CsF–Al 2 O 3 system was carried out up to 40 mol% Al 2 O 3 . CsF–Al 2 O 3 solidified mixtures have been investigated using high-field solid-state NMR ( 133 Cs, 27 Al, and 19 F) spectroscopy and X-ray powder diffraction over a broad range of compositions with synchrotron powder diffraction and Rietveld analysis. A new cesium oxo-fluoro-aluminate, Cs 2 Al 2 O 3 F 2, was discovered, prepared, and structurally analyzed by synchrotron diffraction analysis. In addition to Cs 2 Al 2 O 3 F 2, we have synthesized the following pure compounds in order to aid in the interpretation of NMR spectra of the solidified samples: CsAlF 4, Cs 3 AlF 6, and CsAlO 2 .

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.
