This paper researched the fabrication of perovskite (CaTiO3) synroc by combustion synthesis (CS) and the characterization of the products. This synthesis process is simpler, the fabricated synroc can immobilize waste loading up to wt( 36%) SrO with satisfied physical properties (density>4.2 g•cm-3, open porosity<0.2%). The microstructure analyses by XRD and SEM/TEM show that the major phase is perovskite which well agrees with the design. It proves that CS offer a suitable Sr-waste into perovskite (CaTiO3) synroc which is favorable for geological disposal.
