Abstract:A phosphate glass‐ceramic wasteform incorporating cerium monazite was synthesized through a two‐step solid phase sintering methodology, aimed at immobilizing waste salts derived from the pyrochemical reprocessing of spent nuclear fuel. The initial phase involved the synthesis of cerium monazite powder, employing a stoichiometric mixture of CeF3 and NH4H2PO4 in a molar ratio of mol(Ce:PO4) = 1:1.4, which was subjected to a thermal treatment at 900°C. Subsequently, the glass‐ceramic matrix was fabricated by sint… Show more
