  • Titanate are one of the important candidates for solidifying high-level radioactive nuclear waste (HLW) and lanthanide (Plutonium) due to its excellent physical and chemical durability. Polycrystalline Lu2Ti2O7 and Lu2TiO5 ceramic materials were prepared by a conventional ceramic sintering process, then the samples were irradiated with 800 keV Kr2+ at room temperature, and were subsequently characterized by GIXRD method. In the two kinds of samples, lattice swelling was observed firstly, and then amorphization phase transition took place. However, the lattice swelling of Lu2Ti2O7 is greater than that of Lu2TiO5. In addition, when Lu2Ti2O7 and Lu2TiO5 were irradiated to a fluence of 2×1014 ions/cm2, the amorphous content of Lu2TiO5 sample reaches 95.54%, while the amorphous content of Lu2Ti2O7 sample is only 74.66%. The first-principle was used to calculate the lattice swelling of Lu2Ti2O7 with increasing of anti-sites concentration. The results show that the lattice swelling of Lu2Ti2O7 before amorphization is mainly caused by the cation anti-sites. While the pristine Lu2TiO5 is a disordered fluorite structure, so that no cation anti-sites will contribute to the lattice swelling of Lu2TiO during the ion irradiation process. Therefore, the lattice swelling of Lu2TiO5 is lower compared to that of Lu2Ti2O7.

Abstract: Titanate are one of the important candidates for solidifying high-level radioactive nuclear waste (HLW) and lanthanide (Plutonium) due to its excellent physical and chemical durability. Polycrystalline Lu2Ti2O7 and Lu2TiO5 ceramic materials were prepared by a conventional ceramic sintering process, then the samples were irradiated with 800 keV Kr2+ at room temperature, and were subsequently characterized by GIXRD method. In the two kinds of samples, lattice swelling was observed firstly, and then amorphization phase transition took place. However, the lattice swelling of Lu2Ti2O7 is greater than that of Lu2TiO5. In addition, when Lu2Ti2O7 and Lu2TiO5 were irradiated to a fluence of 2×1014 ions/cm2, the amorphous content of Lu2TiO5 sample reaches 95.54%, while the amorphous content of Lu2Ti2O7 sample is only 74.66%. The first-principle was used to calculate the lattice swelling of Lu2Ti2O7 with increasing of anti-sites concentration. The results show that the lattice swelling of Lu2Ti2O7 before amorphization is mainly caused by the cation anti-sites. While the pristine Lu2TiO5 is a disordered fluorite structure, so that no cation anti-sites will contribute to the lattice swelling of Lu2TiO during the ion irradiation process. Therefore, the lattice swelling of Lu2TiO5 is lower compared to that of Lu2Ti2O7.
