The density, refractive index, molar refractivity, and infrared absorption spectra of soda aluminosilicate glasses containing up to 34.8 wt% alumina have been determined. Changes in these properties with composition can be explained by existing theories which assume that the aluminum ions form only A10 4 tetrahedra when the Al/Na ratio of the glass is equal to or less than 1. The aluminum ions in glasses having an Al/Na ratio larger than 1 are in both fourfold and sixfold coordination.
