Preparation method of radioactive solid waste fluorapatite solidified body
The invention discloses a preparation method of a radioactive solid waste fluorapatite solidified body, and relates to the technical field of radioactive solid waste solidification treatment. The preparation process of the radioactive solid waste fluorapatite solidified body comprises the following steps: firstly, taking 264.0-92.26% by weight of Ca3 (PO4), 25.37-7.74% by weight of CaF and 0-30.62% by weight of radioactive solid waste for batching, then grinding into solid powder by using a ball mill, then carrying out dry pressing on the solid powder into a blank, then putting the blank into a pulse microwave generator, reacting for 6-48 hours at the constant temperature of 800-1400 DEG C, and finally naturally cooling, and obtaining the radioactive solid waste fluorapatite solidified body. The radioactive solid waste fluorapatite solidified body prepared through the method is good in chemical stability and thermal stability and high in leaching resistance. The method is low in cost, and a new method is provided for high-level waste man-made rock solidification.
本发明公开了一种放射性固体废物氟磷灰石固化体的制备方法，涉及放射性固体废物固化处理技术领域。放射性固体废物氟磷灰石固化体的制备流程如下：先按重量百分比，取Ca3(PO4)264.0～92.26％、CaF25.37～7.74％、放射性固体废物0～30.62％进行配料，然后用球磨机将其研磨成固态粉末，再将固态粉末干压成胚体，之后将胚体置于脉冲微波发生器，于800～1400℃的恒温下反应6h～48h，最后让其自然冷却，即得放射性固体废物氟磷灰石固化体。采用本发明方法制备的放射性固体废物氟磷灰石固化体化学稳定性和热稳定性好、抗浸出性能强。本发明方法成本低廉、为高放废物人造岩石固化提供了新方法。
