Paper Title:
Immobilization of Radioactive Wastes into CaTiO3 Synroc by the SHS Method
  Abstract

This paper researched the fabrication of perovskite (CaTiO3) synroc by self-propagating high temperature synthesis (SHS) and the characterization of the products. This synthesis process is simpler, the fabricated synroc can immobilize waste loading up to wt( 35%) SrO with satisfied physical properties (density>4.2 g•cm-3, open porosity<0.2%). The microstructure analyses by XRD and SEM/EDS show that the major phase is perovskite which well agrees with the design. It proves that SHS offer a suitable Sr-waste synroc which is favorable for geological disposal.
