In this work, transparent Y2O3 ceramics were obtained by direct ink writing (DIW) followed by vacuum sintering at 1720°C for 32 h. The optimal ink composition was identified as 78 wt.% of solid loading, 1.5 wt.% of Dolapix CE64, 8 wt.% of Pluronic and 5 wt.% of ethylene glycol. The ink exhibits pseudoplastic behaviour and optimal viscoelastic properties for printing. Transparent Y2O3 ceramics were characterized by mostly uniform dense microstructure with the presence of some large defects caused by the printing process. In-line transmittance of the obtained ceramics is 43 % in the range of 3–5 μm.

Abstract
In this work, transparent Y2O3 ceramics were obtained by direct ink writing (DIW) followed by vacuum sintering at 1720°C for 32 h. The optimal ink composition was identified as 78 wt.% of solid loading, 1.5 wt.% of Dolapix CE64, 8 wt.% of Pluronic and 5 wt.% of ethylene glycol. The ink exhibits pseudoplastic behaviour and optimal viscoelastic properties for printing. Transparent Y2O3 ceramics were characterized by mostly uniform dense microstructure with the presence of some large defects caused by the printing process. In-line transmittance of the obtained ceramics is 43 % in the range of 3–5 μm.File in questo prodotto:
