Highly compact green bodies are usually required to fabricate transparent or translucent polycrystalline yttrium oxide. The present work reports on the fabrication of highly dense (ρrel >98%) Y2O3 from low-density by exploiting a high sinterability nano powder. A commercial Y2O3, with crystallite size ca. 30 nm, was shaped uniaxial pressing and, afterwards, densified pre-sintering at 1500 °C fo...
