Abstract

There are various types of silica glasses made by different methods. They contain, in general, different levels of impurities such as sodium oxide, alumina and hydroxyls and have different fictive temperatures. Some investigators [1-3] reported anomalous electric and dielectric properties of silica glasses and attributed these anomalies to impurities. In order to resolve the cause of these anomalies, electric and dielectric properties of various silica glasses were measured as a function of temperatures [4-6].
