A New Model for the Structure of Silica Glass

Abstract

A new model is presented for the structure of silica glass. This modulated network model is a direct heir not only to the continuous random network model of Zachariasen, but also to the microcrystalline model of Phillips. It consists of domains of six-ring networks linked by interfacial material containing rings of other sizes. The model is supported by some new geometrical theorems which lead to important restrictions on the network topology. Keywords: Glasses, Order-disorder.
