Abstract
Applications of SAXS to structural studies of oxide glasses are reviewed. The evolution in the basic understanding of the
mechanisms involved in microphase separation in borate glasses is presented. Experimental SAXS results and their comparison
with classical theories of spinodal decomposition and more recent statistical theories are discussed. Other applications of
SAXS, such as the structural characterization of the " sol-gel route " to obtain silica glasses is outlined.
