In this work, Strontium Titanate samples were synthsized by self-propagating high-temperature synthesis (SHS). Sr2+ directly took part in the synthesis process. As a result, immobilization limitation issue is basically resolved. The Strontium titanate was characterized by crystal structure, dense properties, leach rate, microstructure and scanning electron microscopy. 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.
