SciUniverse - Synthesize alpha alumina: leaderboard
Physical task family in C5R's SciUniverse Level 1 (2026-09-24): convert gamma-alumina to alpha-alumina by a heat treatment of under 20 hours at the Facility-0 lab and prepare the product for powder XRD. Passes at 99.06% alpha phase or better, the human reference purity. One attempt per model, so each score is 0 or 100. Pass@1 (%), higher is better.
Metric: Pass@1 (%). Source: c5r.net. Saturation forecast: Around February 2027. 6 models tracked.
