Abstract
The carbothermic reduction of MoS2 using Mg, an efficient sulfur scavenger, was carried out by two very different routes, i.e., mechanochemical reaction and heat treatment. The thermodynamic calculation results show that Mo2C and MgS are the phases formed when the elements are combined, and carbothermic reduction of molybdenite takes place. XRD analysis data indicates no reaction occurred at 1, 2, and 5 h of milling by the mechanochemical method, and the initial phases MoS2, Mg, and C were identified. On the other hand, after 7 hours of milling, Mo2C and MgS phases finally emerged. Through heat treatment, the desired Mo2C and MgS phases were successfully prepared with the crystal diffraction spots obvious at 700, 800, and 900 °C, respectively. Both of these methods produced powders which were then washed with a 10% 1M HCl solution, and as a result, a reasonable yield of pure molybdenum carbide was obtained.

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
