description The invention discloses a composite solidification method for high-capacity radioactive wastes utilizing Gd2(CO3)3 and high-level aftertreatment oxides as raw materials. The method comprises the steps: firstly, analyzing the composition and the content of the high-level aftertreatment oxide, and performing a solidified body formulation design by utilizing Gd2(CO3)3 and the high-level aftertreatment oxides as the raw materials; and then, mixing, thining and pre-pressing the raw materials; and preparing a composite solidified body through a high-temperature furnace and a microwave sintering furnace. The method of the invention is simple in technical operation, high in production efficiency and good in repeatability, and can prepare a radioactive nuclide solidified body with stable performance and be extensively applied to a large-scale treatment of radioactive nuclide wastes discharged from such relative fields as nuclear power station and the like.
