7th Materials Webinar

Synthesis and Sintering of High Entropy Ceramics

Complex ceramics solid solutions are currently attracting a growing scientific interest due to their unique combination of functional and mechanical properties. In particular, the entropy-driven stabilization of new phases and compositions represents a kind of new “far west for ceramurgists”: this approach allows the development of novel materials with still unexplored properties. Moreover, the presence of different cations (typically 5+) in the high entropy ceramics (HEC) structures allows a fine-tuning of their properties by tuning their composition in a multidimensional space.

Due to their complex composition, high entropy ceramics require advanced processing routes, often aided also by the development of predictive models to define their thermal stability. As such, HECs have been manufactured by various synthesis processes, including sol-gel processing, wet-chemical synthesis, spray pyrolysis, solid-state synthesis, and others. Also, various sintering processes have been applied to high entropy ceramics like SPS, flash sintering, UHS, and conventional sintering.

In this webinar, we will present some of the last results regarding the synthesis of novel high entropy rock salts, fluorites, and carbides with a specific focus also on the use of innovative processing/sintering routes.

Bio
Mattia Biesuz got a Ph.D. in “Materials Engineering” at the University of Trento (Italy) in 2017 defending a thesis on the flash sintering mechanisms in alumina and glass-containing alumina ceramics. Since then, he had several research experiences as a PostDoc in China, UK, Czech Republic, and Italy. His research interests currently include various sintering technologies for ceramics consolidation (flash sintering, spark plasma sintering, cold sintering, ultrafast high-temperature sintering), field-assisted ion exchange in glasses and glass-ceramics, porous materials, polymer-derived ceramics, and high-entropy compounds. His research has been mostly focused on underlying the peculiar physical-chemical effects activated by electric fields during ceramics processing. To date, he has published 78 manuscripts. His works have been awarded the “Pfeil Award” (Institute of Materials, Minerals and Mining, UK, 2020), “MRS Postdoctoral Award” (2022), the “Best Paper Award” in the Journal of the Asian Ceramics Societies (2019). He is an associate editor of Materials, and a member of MRS and ICerS.
