Structural modifications of GeO glass under high pressure and high temperature
Antoine Cornet, Remy Molherac, Bernard Champagnon +1
Vitreous GeO has been compressed at high temperature, to investigate the effect of thermal activation on the structural reorganization during compression. The measurements were…
Evidence of polyamorphic transitions during densified SiO glass annealing
Antoine Cornet, Christine Martinet, Valerie Martinez +1
In-situ X-ray scattering monitoring is carried out during temperature annealing on different densified SiO glasses. Density fluctuations and intermediate range coherence from x…
Relaxation processes of densified silica glass
Antoine Cornet, Valerie Martinez, Dominique de Ligny +2
Densified SiO2 glasses, obtained from different pressure and temperature routes have been annealed over a wide range of temperature far below the glass transition temperature (500$…
Permanently densified SiO glasses: a structural approach
Christine Martinet, Assia Kassir-Bodon, Thierry Deschamps +4
Densified silica can be obtained by different pressure and temperature paths and for different stress conditions, hydrostatic or including shear. The density is usually the macrosc…
