Abstract

Sintering and microstructural development in ceramics has long been studied in a two-dimensional grain size-density space, with only texture (i.e. deviation of grain orientation from random) used to gain first insights into additional parametric spaces. Following an increased interest for grain boundary engineering and a deeper understanding of dopant effects on sintering and grain boundaries, the theory of complexion transitions for ceramics has been introduced over the last decade, providing a new base for advanced microstructure engineering in ceramics. With emergence of high entropy ceramics over the last 5 years, the combination of both yields new grounds for exploration and engineering of functional ceramic materials of the future.
