Abstract

We report evidence for long-range structural fluctuations in a CaO-Al2O3-2SiO2 glass of homogeneous composition. Our new experimental method is based on spatial variations in the electron energy-loss near-edge spectroscopy (ELNES), using the small focused probe of an electron microscope. The results are obtained from the average of the short to medium-range structures around Al and Si, which are obtained by comparing experimental data in the glass with calculations of the local density of states in a compositionally equivalent (anorthite) crystal.
