Abstract
The formation and structure of GeO2, dense octahedral and high pressure glass, were analyzed. The study was carried out by using x-ray and neutron-diffraction measurements and molecular dynamics simulation under pressure effects. It was observed that the structures with a constant average coordination of ∼ 5, indicating a metastable, intermediate form of the glass. It was also observed that, the pressure-induced changes in GeO 2 probably result from a decrease in size and eventual collapse of the ambient-pressure cage structures as the network was compacted.
