Density and density fluctuations anomalies of SiO2 glass:comparison and light scattering study.

Abstract

The objective of this work is to compare density and density fluctuations of silica as function of temperature in the anomalous domain between 950°C and 1480°C by comparing Archimedes' macroscopic measurements and light scattering. A parallel qualitative behaviour is observed between density fluctuations and macroscopic density. Density fluctuations of silica show a minimum as function of the temperature as the macroscopic density does: this correlation indicate a possible common origin of both observations.
