| Abstract Scope |
Achieving high-quality, ceramic components via additive manufacturing or powder injection molding requires both optimal powder morphology and effective debinding and sintering strategies. The work demonstrates how controlling the shape of uranium dioxide (UO₂) powder can significantly increase the solids loading in polymer feedstocks. Spherical UO₂ particles were produced by formulating a specialized slurry that is subsequently sprayed and frozen. The spherical morphology enabled a 50% volume loading in a polymer matrix, resulting in a cohesive feedstock compared to feedstocks made from irregularly shaped powders. The improved rheological properties allowed testing the extrusion of the filaments for 3D printing, enabling the fabrication of complex geometries that are otherwise unachievable through traditional manufacturing methods. This work highlights the critical role of powder morphology in advanced manufacturing of ceramic nuclear fuels and opens new avenues for producing intricate, high-performance UO₂ components. |
