Abstract
Porous silicon carbide (SiC) ceramics with porosities ranging from 60% to 83% were fabricated from extruded blends of carbon‐filled polysiloxane using expandable microspheres as sacrificial templates. The fabrication process involved the following steps: (i) extrusion and in situ foaming of a mixture of polysiloxane, carbon black (used as a carbon source), Al 2 O 3 –Y 2 O 3 (used as a sintering additive), expandable microspheres (used as sacrificial templates), and SiC (an optional inert filler); (ii) cross linking the polysiloxane in the extruded blends; (iii) transforming the polysiloxane by pyrolysis into silicon oxycarbide; and (iv) fabricating porous SiC ceramics by carbothermal reduction and subsequent sintering.

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
