Dehydration of lithium dihydrogenphosphate in a ball‐mill rotary‐kiln ( <scp>BaMRoK</scp> ) reactor
Bibliographic record
Abstract
Abstract Lithium dihydrogenphosphate (LHP) needs to be dehydrated to be safely applied for the melt casting process to produce lithium iron phosphate (LFP). The dehydration reaction consists of several consecutive melting, oligomerization, and crystallization steps resulting in a solid product stuck to the reaction vessel at around 400°C. Here we applied an electrical shell‐heated rotary kiln containing grinding media (ball‐mill rotary‐kiln, BaMRoK) to dehydrate LHP at 400°C and recover the ground product without needing any extra processing. The bulk convective heat transfer coefficient of the kiln has been calculated in the presence of the grinding media and the temperature profile has been modelled using COMSOL Multiphysics. The kinetic model of the reaction from thermogravimetric analysis (TGA) and the thermal profile suggest that the dehydration reaction mostly happens on the internal surface of the BaMRoK wall.

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.
