陶瓷是一类重要的材料，具有广泛的应用，因为它的高热，机械。还有化学稳定性。基于第一性原理方法的计算预测可以成为加速材料发现以开发改进陶瓷的有价值的工具。必须通过实验来证实这种预测的材料特性。然而，在传统的陶瓷烧结技术中，由于加工时间长和挥发性元素损失导致的成分控制不佳，限制了材料的筛选率。为了克服这些限制，我们开发了一种在惰性气氛下通过辐射加热制备陶瓷材料的超快高温烧结（UHS）工艺。我们提供了几个UHS工艺的例子来展示其潜在的实用性和应用，包括固态电解质、多组分结构和高通量材料筛选方面的进展。
Ceramics are an important class of materials with widespread applications because of their high thermal, mechanical. and chemical stability. Computational predictions based on first principles methods can be a valuable tool in accelerating materials discovery to develop improved ceramics. It is essential to experimentally confirm the material properties of such predictions. However, materials screening rates are limited by the long processing times and the poor compositional control from volatile element loss in conventional ceramic sintering techniques. To overcome these limitations, we developed an ultrafast high-temperature sintering (UHS) process for the fabrication of ceramic materials by radiative heating under an inert atmosphere. We provide several examples of the UHS process to demonstrate its potential utility and applications, including advancements in solid-state electrolytes, mufticomponent structures, and high-throughput materials screening.
