Effects of Tin on the Physical Properties and Crack Growth in Soda-Lime-Silica Float Glass

Abstract

The effect of tin on the properties of soda-lime-silica glass was examined with glasses doped with 0.2-3.0-mol % SnO2. Trends in the properties are consistent with an increase in the network connectivity with increasing tin concentration. The difference in the thermo-elastic properties of the tin doped glass suggests the creation of residual stresses in the near surface region of float glass, resulting form the tin concentration gradient during cooling. Two-point fiber bend tests were conducted to determine the effect of tin on the stress corrosion susceptibility of tin doped soda-lime-silica glasses. The results showed the stress corrosion exponent for the tin-doped glasses to be a weak positive function of tin concentration.
