Electron Irradiation Effects of SrZrO3 Ceramic for Radioactive Strontium Immobilization

The perovskite structure is widely considered ideal host phases for Sr immobilization. To investigate the radiation tolerance on ceramic waste forms, the as-prepared SrZrO3 ceramics were irradiated by external electron beam. The results indicated that the electron irradiation had different influence on the surface and inside of the SrZrO3 ceramic. The no-crystallizing can be produced on the surface of SrZrO3 ceramic, and electron beam heating promoted grain growth in the inside of SrZrO3.
