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 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.
