| Abstract Scope |
This talk will first review our recent studies on the scientific questions and technological opportunities of flash sintering using ZnO as a model system [Scripta Mater. 146: 260 (2018)]. A thermal runaway model has been developed to forecast the onset flash temperatures [Acta Mater. 94:87 (2015)]. The rapid heating profiles enable the ultrafast densification rates [Acta Mater. 125:465 (2017)]. A two-step flash sintering (TSFS) technology was invented to densify ceramics with suppressed grain growth [Scripta Mater. 141:6 (2017)]. Using water-assisted flash sintering (WAFS), we can start a flash at room temperature to subsequently densify a ZnO specimen to ~98% densities in 30 s [Scripta Mater. 142:79 (2018)]. Flash spark plasmas sintering was used to sinter high-entropy ultrahigh temperature ceramics for potential applications in extreme environments [Scripta Mater. 170:106 (2018)]. Our most recent ongoing research in several related areas, including materials for energy applications, will also be presented and discussed. |
