Phases Formed in Al-Doped Ni[sub 1/3]Mn[sub 1/3]Co[sub 1/3](OH)[sub 2] Prepared by Coprecipitation: Formation of Layered Double Hydroxide
Bibliographic record
Abstract
The coprecipitation process, using either mixed nitrate or sulfate solutions, to produce Al-doped has been studied in detail. Using X-ray diffraction (XRD) and thermal gravimetric analysis (TGA), it has been determined that charge-compensating or ions accompany the incorporated ions into the structure to form layered double hydroxides (LDHs). The phases formed were determined for in and . For , two phase mixtures between ( , Mn, and Co) and the LDH phase with were formed. For aluminum contents greater than , XRD and TGA experiments suggest that the excess Al is present as and that the product is a mixture of or and , where M represents the mixture of Ni, Mn, and Co. Alternatively, the data can also be explained assuming that samples with are single phase . TGA experiments show that the in the -containing LDH is eliminated at lower temperature than the in the -containing LDH. Thus coprecipitations using nitrates may be preferred in situations where excellent cation mixing is desired in the production of Al-doped .

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.
