| Abstract | Synroc is recognized as the second generation waste form for the disposal of high-level radioactive waste (HLW). In this research, one of the mostly studied Synroc minerals, perovskite (CaTiO3 ), was prepared by self-propagating high-temperature synthesis (SHS). Nd2O3 and Al2O3 were employed as the oxidants with Ni as the reductant. Perovskite was successfully synthesized. The as-synthesized samples were readily solidi-fied with desirable density and Vickers hardness. |
