Enhancing Functional and Structural Properties of Advanced Materials through Scandium-based Nanostructures: Applications in Ceramics, Thermoelectrics, Memory Devices, and High-Strength Alloys
Abstract: This study explores the fabrication and properties of scandium-based nanostructured materials with applications in ceramics, glass, thermoelectric modules, switching devices, and strengthened alloys. Scandium oxide (Sc₂O₃) nanopowders were synthesized using precipitation techniques and subsequently sintered to create transparent ceramics with fine dispersion. Investigations into scandium-doped metallic glasses demonstrated enhanced plastic deformation, with notable tensile plasticity attributed to its unique nanoglass structure. A new scandium-doped thermoelectric material, ZnCdO, was also developed, …
