Abstract

Submicrometer grain-sized (1.5 µm) yttria ceramics exhibited the remarkable flexural strength enhancement from 28.5 to 165.0 MPa, and equivalent or superior transparency (81.8%, 1064 nm) to that of single crystal under the two-step sintering of 1550–1500 °C and Al₂O₃ additive amount of only 150 ppm.
