Transparent Alumina/Ceria Nanocomposites By Spark Plasma Sintering [PDF]

Advanced Engineering Materials, 2010
AbstractThe influence of oxides (such as MgO, TiO2, CaO, etc.) on the transparency of polycrystalline alumina compacts are widely studied in the literature. In this work, a completely different approach is developed, consisting of precipitating 0.5 wt.‐% CeO2 nanoparticles (< 5 nm) on the surface of the starting alumina nanopowder (d50 approximately
