Self‐Propagating High‐Temperature Synthesis of Zirconolite Using CuO and MoO 3 as the Oxidants
Source abstract
Abstract
Synroc is recognized as the second generation waste form for the disposal of high‐level radioactive waste ( HLW ). In this research, one of the mostly studied Synroc minerals, zirconolite (CaZrTi 2 O 7 ), was prepared by self‐propagating high‐temperature synthesis ( SHS ). CuO and MoO 3 were employed as the oxidants with Ti as the reductant. Different TiO 2 /Ti ratios were selected to investigate reactivity and adiabatic temperature ( T ad ) of the designed SHS reactions. Zirconolite was successfully synthesized as the main phase at varied TiO 2 /Ti ratios using CuO and MoO 3 as the oxidants. The as‐synthesized samples were readily solidified with desirable density and Vickers hardness.
