Some physical properties of SnO-SiO2 glasses with SnO contents ranging from 17 to 72 mol% have been measured including density molar volume, thermal expansion, refractive index and molar refractivity. The ability of this glass system to form glass past the orthosilicate composition has been discussed in terms of the polarising power of Sn2+ and the structure of SnO. Variation of the physical properties with composition can be explained in terms of the molar volume, oxygen molar volume and molar refractivity of the glass. Discontinuities in the region of 30-45 mol% SnO are observed for the variation of the physical properties with composition. The discontinuities are related to a change in the structural role of SnO from that of modifier at low SnO content to intermediate at higher SnO content. This type of behaviour is substantiated by earlier results on Sn-119 Mossbauer spectroscopy and Si-29 NMR.
