This manuscript highlights the fabrication of high-performance alumina-based nanostructured materials which reach transparency. This work presents the influence of the addition of small quantities of a ceria precursor on the transparency of polycrystalline alumina-based composite materials with different sintering atmospheres by Spark Plasma Sintering. Green density and alumina grain growth inhibition promoted by CeOx precipitates are found to be responsible for the enhancement in transmittance with respect to pure alumina.
