The study of multi-phase rare-earth phosphate-borosilicate glass composites synthesized by the ceramic method via a 1-step pathway
Bibliographic record
Abstract
Multi-phase glass-ceramic composites (i.e., composite materials containing multiple ceramic crystallites dispersed in a glass matrix) that have applications as potential nuclear waste form materials have been synthesized and examined. Crystallites of xenotime-type (YPO 4 ) phosphates and monazite-type (LaPO 4 ) phosphates were dispersed in borosilicate glass . The composition of the glass matrix was varied to eliminate the formation of unwanted secondary phases. Powder X-ray diffraction (XRD), X-ray absorption near-edge spectroscopy (XANES), Scanning Electron Microscopy (SEM), and Energy-Dispersive X-ray spectroscopy (EDX) were employed to investigate the long-range order, local chemical environment, and morphology of the composite materials. The XRD patterns and XANES spectra revealed the exclusive presence of LaPO 4 and YPO 4 phases within the composite subsequent to the modification of the glass matrix. The SEM images and EDX maps collected from these composite materials also showed only the presence of LaPO 4 and YPO 4 after modification of the glass composition by removing Na 2 O and CaO.

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.
