Abstract
Abstract Coprecipitation characteristics of CaCO 3 and CaSO 4 were studied under various operating conditions. The investigations were carried out in temperature‐controlled batch tests. Coprecipitation results were compared with our experimental results of a single salt crystallization. It was found that the induction period and kinetics of coprecipitation of these two salts follow that of pure CaCO 3 . However, thermodynamic concentrations of Ca in coprecipitation followed that of pure CaSO 4 at all times. The relationship between the thermodynamic concentrations of Ca for pure CaCO 3 and CaSO 4 solutions depended on the pH of the CaCO 3 solution. CaSO 4 precipitated in form of gypsum and had a needle shape structure; CaCO 3 had a spiral growth and precipitated in form of calcite. The precipitate structure was affected by the co‐existence of salts; the co‐precipitation resulted in CaCO 3 crystals interwoven by CaSO 4 crystals. This tends to result in a co‐precipitate that is stronger than pure CaSO 4 and weaker than pure CaCO 3 precipitate.

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 it
