- •
UO2 nanoparticles were synthesized by the radiolytic reduction of (NH4)4UO2(CO3)3 with high efficiency.
- •
The as-prepared UO2 nanoparticles were stable in the irradiated mother solution exposed to air atmosphere.
- •
UO2powders could be sintered at 450–600 °C in vacuum, much lower than that in traditional process.
