“…In the P-UHS setup, the sample is completely embedded in the graphite powder bed, the two electrodes are inserted into the graphite powder, and a DC power supply is connected. Similar to graphite felt, the graphite powder used in P-UHS effectively serves as both a heater and a thermal insulator [140]. It is demonstrated that UHS is indeed suitable for heating additively manufactured porous components.…”

This review discusses the groundbreaking advancements in electric current-assisted sintering techniques, specifically Flash Sintering (FS) and Ultrafast High-Temperature Sintering (UHS), for their application in Solid Oxide Fuel Cells (SOFCs). These innovative sintering methods have demonstrated remarkable potential in enhancing the efficiency and quality of SOFC manufacturing by significantly lowering sintering temperatures and durations, thereby mitigating energy consumption and cost. By providing a detailed overview of the mechanisms, process parameters, and material characteristics associated with FS and UHS, this paper sheds light on their pivotal role in the fabrication of SOFC components such as electrolytes, electrodes, multilayered materials, and interconnect coatings. The advantages, challenges, and prospective opportunities of these sintering technologies in propelling SOFC advancements are thoroughly assessed, underlining their transformative impact on the future of clean and efficient energy production technologies.

“…[23] Upscaling to larger lateral dimensions is also possible. [61] As with any high heating rate sintering process, UHS sintering comes with uncertain temperature distributions in the sintered material which is experimentally very difficult to access. Modeling techniques were used to estimate temperature distributions.…”

Novel sintering methods have emerged in the recent past years, which have raised great interest in the scientific community. Relying on electric field effects, high heating rates, the use of mechanical pressure, or hydrothermal conditions, they offer fundamental advantages compared to conventional sintering routes like minimizing the energy consumption and enhancing the process efficiency. This perspective aims at explaining these effects in a general way and presenting the status quo of using them for the processing of high‐performing ceramic materials. In detail, this work focuses on flash sintering, ultrafast high‐temperature sintering, spark plasma sintering, cold sintering, and photonic sintering methods based on different light sources. The specificities, potentials, and limitations of each method are compared, especially in the light of a possible industrialization.

“…This technique enables the densification of specimens even with complex shapes, by using a relatively simple setup if compared to SPS or FSPS. So far it has been applied to different oxide systems [22][23][24][25][26][27][28][29][30][31], glasses [32], carbides [33,34], nitrides [35] and high-entropy borides [36].…”
