To dispose of uranium-contaminated soil, the microwave sintering technology was used. A series of uranium-contaminated soils were successfully immobilized via microwave sintering for 30 min. When the amount of uranium ranges from 0 wt % to 1 wt %, glass phase occurred in saline-alkali soil, purple soil and red soil, while glass with presence of a crystalline phase occurred in yellow soil. The FT-IR analysis showed that the uranium-contaminated soils were mainly consist of [SiO₄] units. The Qⁿ distribution of Si-O tetrahedrons and network connectivity of 1 wt % uranium doped sintered soils were related to the composition of soils. The uranium ions were almost immobilized and evenly distributed in sintered soils. Theoretical results showed that the structures of uranium doped sintered soils were made of Si-O, Al-O and Fe-O tetrahedrons. The O-Si-O linkage was the most preferred one among all linkages and the network forming ability of Si was higher than Al.

为了处理受铀污染的土壤，使用了微波烧结技术。通过微波烧结成功地固定了一系列受铀污染的土壤，时间为30分钟。当铀的量的范围从0重量％至1重量％，玻璃相发生在盐碱土，紫色和红壤，而玻璃与结晶相的存在发生在土黄色。FT-IR分析表明，铀污染土壤主要由[SiO ₄ ]单元组成。Si-O四面体的Q ⁿ分布和1 wt的网络连通性掺铀的烧结土壤的百分含量与土壤的成分有关。铀离子几乎固定并均匀分布在烧结土壤中。理论结果表明，掺铀烧结土的结构由Si-O，Al-O和Fe-O四面体组成。O-Si-O键是所有键中最优选的一种，并且Si的网络形成能力高于Al。
