This paper reviews key properties, applications, and examples of ceramic−metal composites (cermets) and metal matrix composites (MMCs) with emphasis on their applicability as waste forms for immobilizing nuclear waste. While the literature is mature for vitrified and cementitious radioactive waste forms, cermet materials have not received adequate attention as potential candidates for immobilizing nuclear waste. To promulgate this effort, this review connects cermet and MMC design, such as hardened tools, with the chemistry of radioactive waste streams. This paper includes a discussion on certification and qualification standards for cermet waste forms, literature gaps, and "how-to" sections on cermet processing techniques. Key parameters discussed include thermal conductivity, chemical durability, and waste loading, as well as examples for metal-containing waste forms. As cermet waste forms gain momentum within the community, this review paper aims to ensure the end-of-life nuclear fuel cycle is addressed from a materials and waste disposition perspective.

“…Besides the electrolyte, there is also research showing the potential application of UHS in other materials for SOFCs. As shown in Figure 16, Guo et al [131] applied UHS to a sinter cermet system composed using the Ni-based superalloy and YSZ, realizing high-density and homogeneous microstructures while minimizing the evaporation of Ni metal due to the reduced sintering time. The results demonstrated that the cermet composed of a Ni-based superalloy and YSZ, which was sintered using UHS, exhibited exceptional mechanical properties and high-temperature oxidation resistance.…”

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.

Bimetallic alloy nanomaterials are promising anode materials for potassium‐ion batteries (KIBs) due to their high electrochemical performance. The most well‐adopted fabrication method for bimetallic alloy nanomaterials is tube furnace annealing (TFA) synthesis, which can hardly satisfy the trade‐off among granularity, dispersity and grain coarsening due to mutual constraints. Herein, we report a facile, scalable and ultrafast high‐temperature radiation (HTR) method for the fabrication of a library of ultrafine bimetallic alloys with narrow size distribution (≈10–20 nm), uniform dispersion and high loading. The metal‐anchor containing heteroatoms (i.e., O and N), ultrarapid heating/cooling rate (≈103 K s−1) and super‐short heating duration (several seconds) synergistically contribute to the successful synthesis of small‐sized alloy anodes. As a proof‐of‐concept demonstration, the as‐prepared BiSb‐HTR anode shows ultrahigh stability indicated by negligible degradation after 800 cycles. The in situ X‐ray diffraction reveals the K+ storage mechanism of BiSb‐HTR. This study can shed light on the new, rapid and scalable nanomanufacturing of high‐quality bimetallic alloys toward extended applications of energy storage, energy conversion and electrocatalysis.
