Description
Little is known about how colloidal processing methods affect the microstructural features and, in turn, mechanical properties of transparent yttrium oxide. In this work, commercial nano-Y2O3 was considered and shaped by consolidating yttria-ethanol suspension using conventional slip casting and pressure filtration at various applied pressures. The samples were densified by pre-sintering in air, with subsequent hot isostatic pressing. The produced samples were then characterized in terms of the final density, grain size, optical transparency, and indentation fracture toughness to define the impact of shaping parameters on grain growth and the final performance of the nano-Y2O3.
