Characterization of agglomeration state in nanocrystalline 3YSZ powders through pressure-displacement curves and nanoindentation of green compacts

► 3YSZ nanopowders calcined at temperatures ≤ 700 °C had higher degree of agglomeration ► Powders calcined at temperatures (800 °C and 900 °C) had lower degree of agglomeration ► Powders calcined at 800 °C and 900 °C showed highest sintered density of 93% of TD ► Powders calcined at 470 °C showed lowest sintered density of 87% of TD
