As an optical material, YO transparent ceramics are desirable for application as laser host materials. However, it is difficult to sinter and dense of YO hinders the preparation of high-quality optical ceramics via traditional processes. In this work, we use LaO as a sintering aid for fabricating high-transparency YO ceramics using a vacuum sintering process. It is demonstrated that the in-line optical transmittance of 15.0 at% La-doped YO at a wavelength of 1100 nm achieves a transmittance of 81.2%. A sintering kinetics analysis reveals that a grain-boundary-diffusion-controlled mechanism dominates the faster densification at high La concentrations. It is also shown that both the mechanical and thermal properties of YO transparent ceramics are significantly improved upon the increase of LaO sintering additives. The results indicate that a La-doped YO transparent ceramic is a promising candidate for a laser host material.
