International audience; Seven magnesium-containing aluminoborosilicate glasses, with three to five oxides, have been studied through comprehensive multi-nuclear solid-state NMR (11B, 27Al, 29Si, 23Na, 17O and 25Mg) and Raman spectroscopy. The progres

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 to the w

Tuning glass composition to obtain targeted properties generally relies on empirical approaches. However, a deep understanding of the physical and chemical mechanisms linking glass composition to its structure and properties would enable developing r

A classical molecular dynamics simulation method for the formation of 'dry' gels from boro-aluminosilicate glass structures

Autor: Stéphane Gin, J.M. Delaye, Mélanie Taron

Publikováno v: Journal of Non-Crystalline Solids. 553:120513

In contact with water, glass transforms into amorphous and porous structures called gels. A simulation method based on classical molecular dynamics is proposed here to mimic “dry” gels forming from initial oxide glass structures. Six glass compos
