Glassforming oxides

Silica (Si02) is the most important of the glassforming oxides although the chemical composition of glasses can vary greatly. The main components of commercially important glasses are shown in Table 1. 

The tetrahedral arrangement of atoms in silica lends itself to the formation of a three-dimensional network, which makes up the polymer-like structure of a glass. Glass can be formed from a single oxide or a mixture of oxides. Silicon dioxide is the premier glassforming oxide either by itself or with other oxides. Additives to silica can either enter into...
