Abstract

Strontium Titanate synroc samples were synthesized by combustion cynthesis (CS). Sr directly took part in the synthesis process. As a result, loading content issue is basically resolved. The products were characterized by density, microhardness X-ray diffraction, and scanning electron microscopy (SEM/EDS). The leaching rate was measured by the method of PCT. The results indicate that the Sr2+-SrTiO3 compound with high density, low leach rate and high property stability and the synthesis process is feasible in technology and economy. It can be concluded that the Strontium Titanate synroc is a perfect material to immobilize HLW Keywords: Strontium Titanate, high-level radioactive waste (HLW), immobilization, self –propagating high –temperatures synthesis (SHS).
