Abstract

Abstract

Perovskite synroc samples were synthesized by Self-propagating High-temperature Synthesis (SHS), and their properties, including leach rate, density, microhardness and the largest High Level radioactive Waste (HLW) content held in the samples, were tested by X-ray diffraction and scanning electron microscopy. The results indieate that the Sr²⁺-CaTiO₃ compound with high density are formed and the largest SrO content in the compound can reach 35% in mass fraction. It can be concluded that the perovskite synroc is a perfect material to immobilize HLW.
