Synroc is recognized as the second generation waste form for the immobilization of high-level radioactive waste (HLW). Zirconolite-rich (CaZrTi2O7) Synroc minerals were attempted by self-propagating high-temperature synthesis (SHS) using Fe2O3, CrO3, Ca(NO3)2as the oxidants and Ti as the reductant. All designed reactions were ignited and sustained using Ca(NO3)2as the oxidant, and zirconolite-rich ceramic matrices were successfully prepared with pyrochlore (Ca2Ti2O6), perovskite (CaTiO3) and rutile (TiO2) as the minor phases. The sample CN-4, which was designed using Ca(NO3)2as the oxidant with TiO2/Ti ratio of 7:9, was readily solidified with density of 4.62 g/cm3and Vickers hardness of 1052 HV. CeO2was successfully stabilized by the CN-4 sample with resultant phase constituent of 2M-CaZrTi2O7and CaTiO3.
