Abstract

It was formerly believed that phase separation occurs only in silica-alkaline earth oxide systems, where the drops are fairly large and can be observed with the aid of an optical microscope. Data on low-angle x-ray scattering and the results obtained by other methods indicate that glasses contain microheterogeneity regions of the order of 10 Å in size. The discovery of microcrystalline glasses and extensive applications of electron microscopy revealed micro- phase separation in the size range from 10 Å to several microns in glasses of the most diverse compositions.
