Effect of Zeolite Formation on Borosilicate Glass Dissolution Kinetics

This study is a preliminary work on the description and the modeling of physico-chemical mechanisms potentially causing nuclear glass alteration to accelerate, as observed under experimental specific conditions. A better understanding of the mechanisms of alteration resumption, linked to the precipitation of zeolite, is necessary to model these phenomena. Leaching tests of a nuclear borosilicate glass show guidelines for designing experiments that promote alteration resumption and evidence the role of developed crystalline surfaces and aluminum on nucleation kinetics of zeolites.
