Impact of V2O5 on the Dissolution Behavior of Sodium Aluminoborosilicate‐Based Model Nuclear Waste Glass

International Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Understanding how vanadium oxide (V2O5) influences the dissolution behavior of nuclear waste glasses is essential for optimizing their waste loading and long‐term durability. In this work, a series of sodium aluminoborosilicate‐based model glasses—(100−x) (30Na2O–5Al2O3–15B2O3–50SiO2)—xV2O5, where x = 0, 2.5, and 5 mol.%—were synthesized to ...
