The samples of low-temperature mineral-like magnesium potassium phosphate matrix were synthesized under solidification of aqueous solutions of uranyl nitrate and lanthanum nitrate. The hydrolytic stability of the synthesized samples was studied in accordance with the current regulatory requirements. The structure of a matrix containing lanthanum and the distribution of matrix-forming components were studied. It was shown that the magnesium potassium phosphate matrix is a promising material for conditioning of wastes containing residual amounts of uranium and plutonium after reprocessing spent nuclear fuel, as well as transplutonium and rare-earth elements.
