Abstract

Read online

High-surface-area corundum are used in ceramics and catalyst supports, yet the synthesis is hampered by high energy barrier and aggregation. Here the authors report the ultrafast synthesis of corundum nanoparticles via the resistive hotspot triggered phase transformation in electric heating process.
