Abstract Conventional ceramic sintering often requires high temperatures and hours of duration to achieve near full density. Herein, we adopted an innovative ultrafast high-temperature sintering (UHS) technique to densify several representative bulk oxides within an isothermal duration of 30 s and a total sintering period of several minutes, and revealed the relationship between ceramic structures and processing parameters. These achievements demonstrate the great potential of the UHS technique in the rapid densification of ceramics. Moreover, this flexible technique is expected to accelerate the material screening rate and facilitate the development of novel materials.

块状氧化物的超快高温烧结

摘要 传统的陶瓷烧结通常需要高温和数小时的持续时间才能达到接近全密度。在此，我们采用了创新的超快高温烧结 (UHS) 技术，在 30 秒的等温持续时间和几分钟的总烧结时间内致密了几种具有代表性的块状氧化物，并揭示了陶瓷结构与工艺参数之间的关系。这些成就证明了 UHS 技术在陶瓷快速致密化方面的巨大潜力。此外，这种灵活的技术有望加快材料筛选率并促进新材料的开发。
