Fabrication of Highly Transparent Y(2)O(3) Ceramics with CaO as Sintering Aid

Highly transparent Y(2)O(3) ceramics were successfully fabricated with CaO as sintering aid. The microstructure evolution, optical transmittance, hardness and thermal conductivity of the Y(2)O(3) ceramics were investigated.

Sumario:Highly transparent Y(2)O(3) ceramics were successfully fabricated with CaO as sintering aid. The microstructure evolution, optical transmittance, hardness and thermal conductivity of the Y(2)O(3) 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 Y(2)O(3). With an optimized CaO dosage of 0.02 wt.% combined with the low temperature vacuum sintering plus hot isostatic pressing (HIP-ing), Y(2)O(3) ceramics with in-line transmittance of 84.87% at 1200 nm and 81.4% at 600 nm were obtained.
