The structural flexibility of langbeinite-type structures to host different cations makes them suitable candidates for the formation of multicomponent actinide nuclear waste forms, but this approach remains underexplored. Here, the authors use an optimized high-temperature molten salt method to synthesize a series of single crystals of Cs2UⅣLn(PO4)3 (Ln = Ce – Nd and Sm – Lu) that can simultaneously immobilize U, Ln, and Cs with enhanced leaching resistance.
