The Effects of Various Sources and Templates on the Microwave‐assisted Synthesis of BZSM‐5 Zeolite
Bibliographic record
Abstract
Abstract Isomorphic substitution of boron into ZSM‐5 zeolite under microwave‐assisted hydrothermal conditions was systematically studied. When microwave treatment and conventional heating were used, BZSM‐5 zeolite could be obtained within one day, whereas the synthesis of BZSM‐5 under conventional hydrothermal conditions took five days at 180 °C. Various parameters that affect the crystallization of BZSM‐5, such as templates, crystallization time, the silicon source and the Si/B ratio were investigated. Systematic variations of these parameters revealed that this zeolite can be obtained from the reaction mixture with optimized ratios of Si/B > 0.6. Among various tested sources, tetraethylorthosilicate (TEOS) turned out to be the best source for synthesis of borosilicate zeolite and further investigations were done with TEOS as silicon source. The obtained products were characterized by XRD, SEM, and IR spectroscopic techniques.

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.
