Investigation of Crystallization of Molecular Sieve AlPO<sub>4</sub>-5 by the Dry Gel Conversion Method
Bibliographic record
Abstract
Crystallization of AlPO 4 -5 (AFI), a representative aluminophosphate-based molecular sieve with AFI topology, was examined under dry gel conversion, in particular, vapor phase transport (VPT) conditions. The VPT approach allows one to “freeze” crystallization at different stages and, therefore, to capture several reactive intermediates, which provide “snapshots” of the crystallization process. These intermediates were characterized by powder X-ray diffraction, Raman spectroscopy, and a combination of several solid-state NMR techniques. The results show that the reactive intermediates have two key features: (1) They bear certain structural characteristics of the target framework. (2) They are fragile and held together by weak bonding interactions. Hydrogen bonding apparently plays a key role in the formation of intermediates and their subsequent transformation to the final AFI structure. An AlPO 4 -5 crystallization mechanism under VPT conditions was proposed.

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.
