Abstract

Highly transparent Y₂O₃ ceramics were successfully fabricated with CaO as sintering aid. The microstructure evolution, optical transmittance, hardness and thermal conductivity of the Y₂O₃ ceramics were investigated. It was found that doping a small amount (0.01–0.15 wt.%) of CaO could greatly improve the densification rate of Y₂O₃ . With an optimized CaO dosage of 0.02 wt.% combined with the low temperature vacuum sintering plus hot isostatic pressing (HIP-ing), Y₂O₃ ceramics with in-line transmittance of 84.87% at 1200 nm and 81.4% at 600 nm were obtained.
