Major research challenges in the field of solid-state sintering are noted following the authors’ recent paper (J. Am. Ceram. Soc. 2017. Vol. 100. P. 2314–2352). They are highlighted in the areas of (i) modeling and simulation (mesoscale as well as macroscale), (ii) microstructural evolution with respect to interface structure, (iii) novel sintering techniques, and (iv) solutions for practical systems.
