Preparation of TiC powders and coatings by electrodeoxidation of solid TiO<sub>2</sub>in molten salts
Bibliographic record
Abstract
Porous TiC nanoparticles have been synthesised from sintered pellets comprising a powder mixture of TiO2 and graphite by electrodeoxidation in molten CaCl2–NaCl eutectic. Electrolysis was conducted at 850°C in argon at an applied constant voltage of 3·1 V. The formation of TiC from the oxides/C mixture occurred at less cathodic potentials than those for electrodeoxidation of TiO2 to titanium metal. No titanium metal was observed during electrolysis, as confirmed by XRD. These findings were consistent with the thermodynamic predictions. It was found that CaTiO3 was formed during electrolysis and all the titanium oxides disappeared after 4 h electrolysis in a eutectic CaCl2–NaCl melt at 850°C, leaving CaTiO3/C/TiC mixtures behind at the cathode. It was also found that the formed CaTiO3 was electrodeoxidised to form TiC by prolonged electrolysis. The present results further demonstrated that an adhesive layer of Ti0·55C0·45 was formed on graphite substrates by electrodeoxidation of TiO2 on the substrates.

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.
