EXAFS and the structure of glass

The relevance of EXAFS for studying the structure of glass is reviewed. Examples are taken from recent work on SiOx films, soda silica glasses, calcium and iron containing mineral glasses and amorphous biogenic phosphates. The sensitivity of the environment of modifiers to the morphology of the glass network is stressed. The concepts underlying a modified random network (MRN) are introduced and are discussed in relation to the rheological and diffusion properties of glasses.
