Transformations in B2O3 glass under pressure
B2O3 is a prototypical glass forming oxide material and is an essential component in many industrial glasses. Unlike SiO2 and GeO2 its structure under ambient conditions is not... -
Density-driven structural transformations in calcium silicate glass
The density-driven structural transformations in the calcium silicate glass CaSiO3 will be investigated at pressures increasing to 17.5 GPa. This glass is one of a family of... -
Polyamorphism in Glassy GeO2
The object of this proposal is to determine, by using neutron diffraction, the nature of the polyamorphic phase transition that occurs in glassy GeO2 with increasing pressure.... -
Pressure-driven transformation of the Al coordination environment in oxide glass
In situ high-pressure neutron diffraction will be used to investigate the pressure-induced transformation of the Al coordination environment in a prototypical aluminosilicate... -
Mechanism of network collapse in strong network glass forming systems
The object of this proposal is to investigate the mechanism of network collapse in the ¿strong¿ network glass forming system GeO2 in the pressure range between 9 and 16 GPa...
