WebFeb 12, 2024 · Flash sintering has received wide attention lately due to its ultrafast densification process at low sintering temperature. However, the deformability of flash-sintered ceramics remains poorly understood. Yttria-stabilized zirconia (YSZ) was processed by flash sintering to study deformation mechanism. WebJan 6, 2024 · Flash Sintering (FS), an electric Field-Assisted Sintering Technique (FAST) [ 1] for the densification of ceramic materials at a greatly reduced temperature and time, has gained widespread attention since it was established in 2010 by Prof. Rishi Raj’s group from the University of Colorado at Boulder.
WebFS is [ 20] a current-assisted sintering technology characterized by rapid densification (matter of few seconds-minutes) and by the simultaneous observation of the flash event, including a thermal runaway of internally generated Joule heating, electrical resistivity abrupt drop, and strong bright light emission. WebAug 10, 2024 · Flash sintering has gained its name due to an extremely short densification process (a few seconds). Cologna et al. [ 2] reported sintering of yttria-stabilized zirconia at 850 °C within less than 5 s. This term was previously used to refer to sintering processes conducted within several minutes [ 5 ].
