Synthesis of carnallite crystal from KCl – MgCl<sub>2</sub> solutions and its characterization
Bibliographic record
Abstract
Abstract Carnallite crystals have been synthesized from KCl – MgCl 2 brine solutions at room temperature (23 °C) using a solvent evaporation technique. The effects of the concentration of potassium chloride (KCl) and magnesium chloride (MgCl 2 ) on growth, structural and mechanical properties of the carnallite crystal is investigated and discussed. Transparent and pseudo-hexagonal shaped carnallite crystals with dimensions of 4 × 5 × 2 mm to 16 × 13 × 3 mm are shown. The carnallite crystals were characterized using powder X-ray diffraction and the lattice parameters were found to be a = 9.575 Å, b = 16.155 Å and c = 22.526 Å, space group: Pnna, Z: 12, α = β = γ = 90° with a unit cell volume, V = 3 485.04 Å 3 . The lattice parameters are found to be in good agreement with standard values and the structure of the crystal is orthorhombic. Vickers micro-hardness testing was carried out to determine the hardness and work hardening coefficient of the carnallite crystals.

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.
