New, Superfast Method for Ceramic Manufacturing Could Open Door to AI-Driven Materials Discovery

Conventional ceramic sintering — the firing step that hardens ceramic materials — typically takes hours, a bottleneck for developing new solid-electrolyte and other functional ceramics. A UMD team led by Professor Liangbing Hu reinvented the process into an ultrafast high-temperature sintering method, sandwiching a pressed ceramic pellet between carbon strips that heat it by radiation and conduction to temperatures up to 3,000°C in under 10 seconds — over 1,000 times faster than a traditional furnace.

Professor Yifei Mo collaborated on the study, published on the cover of Science, which also involved Bao Yang, J.C. Zhao, and Howard Wang at UMD along with researchers at UC San Diego and UCLA.

By collapsing sintering time from tens of hours to seconds, the technique clears a path for rapidly synthesizing and testing the large numbers of candidate materials that computational and AI-driven materials discovery can generate — with applications spanning solid-state batteries, fuel cells, and 3D-printed ceramics. The technology is being commercialized through the UMD spinoff HighT-Tech LLC.
