Abstract
Abstract Ultrafast high‐temperature sintering (UHS) is a joule heating method with an extremely high heating rate (∼10 3 –10 4 °C/min). In this work, commercial ZrB 2 powders were rapidly densified by UHS to >90% relative density within 60 s in vacuum without pressure. Bulk density improved from 75% to 93% of relative density by increasing the sintering duration from 10 to 60 s. The final grain size increases from 2.7 ± 1.1 to 19.0 ± 8.4 μm when the sintering time increased from 10 to 60 s. X‐ray diffraction and energy‐dispersive spectroscopy show crystalline phase and compositional uniformity in ZrB 2 after UHS.
