摘要
To research the structure radiation stability of simulated Gd2Zr2O7-pyrochlore glass-ceramic wasteforms Nd3+, Ce4+ were selected as the simulated nuclide of An3+ and An4+ radionuclides respectively. A series of compounds with the general formula Gd2-xNdxZr2-xCexO7 (0.0≤ x ≤2.0) were prepared by High-temperature sintering method at 1623 K for 48 h in air atmosphere. The heavy-ion irradiation experiments were done at room temperature and atmospheric pressure. The structure and microscopic morphology of Gd2-xNdxZr2-xCexO7 (0.0≤ x ≤2.0) glass-ceramic wasteforms before and after irradiation experiments were investigated by the X-ray diffraction and scanning electron microscopy.
