Effect of structural disorder induced by external irradiation with heavy ions on the alteration of a four oxide borosilicate glass
Autor: Stéphane Gin, Mélanie Taron, Hélène Arena, Jean-Marc Delaye
Publikováno v: npj Materials Degradation, Vol 8, Iss 1, Pp 1-11 (2024)
Abstract The irradiation of glass by heavy ions induces structural damage, generally leading to a decrease in its chemical durability whose amplitude strongly depends on the glass chemical composition. Here, we investigate the effects of irradiation

On the effect of Al on alumino-borosilicate glass chemical durability
Autor: Kamalesh Damodaran, Stéphane Gin, Sathya Narayanasamy, Jean-Marc Delaye
Publikováno v: npj Materials Degradation, Vol 7, Iss 1, Pp 1-9 (2023)
Abstract The chemical durability of borosilicate glass used to confine nuclear wastes is known to vary nonlinearly with their composition, making glass dissolution rate predictions difficult. Here, we focus on the effect of Al, an important oxide of

Aqueous alteration of silicate glass: state of knowledge and perspectives
Autor: Stéphane Gin, Jean-Marc Delaye, Frédéric Angeli, Sophie Schuller
Publikováno v: npj Materials Degradation, Vol 5, Iss 1, Pp 1-20 (2021)
Abstract The question of silicate glass chemical durability is at the heart of many industrial and environmental issues, with certain glasses, such as bioglasses, needing to transform rapidly, while others, like nuclear glasses, extremely slowly. Due

Insights into the mechanisms controlling the residual corrosion rate of borosilicate glasses
Autor: Stephane Gin, Xiaolei Guo, Jean-Marc Delaye, Frédéric Angeli, Kamalesh Damodaran, Véronique Testud, Jincheng Du, Sebastien Kerisit, Seong H. Kim
Publikováno v: npj Materials Degradation, Vol 4, Iss 1, Pp 1-9 (2020)
Abstract Borosilicate glasses are widely used to confine high-level radioactive wastes. The lifetime of these materials could reach hundreds of thousands of years if leaching of the glass into groundwater enables the formation of a passivating gel la
