摘要：

Normalized mass loss and leach rates of elements from the synthesized sodium aluminum phosphate and sodium aluminum iron phosphate glasses in relation to the content of uranium introduced into the glass-forming charge in the form of uranium dioxide or uranyl nitrate were determined by the РСТ procedure (variant А). The relationship between the element leaching parameters and the structure of the anionic motif of the glass network, up to the formation of a polyanionic structure from aluminum (iron)–phosphorus–oxygen network and uranium–oxygen polyanions, was determined. The resistance of the glasses to leaching of elements is on the same level as that of reference iron phosphate glasses. © 2017, Pleiades Publishing, Inc.
