The Thermal Expansion of some Soda-Lime-Silica Glasses
JSGT_1934_V18_T005_T012
The thermal expansions, from room temperature to the softening point, have been determined for a series of pure soda–lime–silica glasses ranging in composition from 70 to 80% SiO2, 2·7 to 14·4% CaO, and 10·5 to 22·7% Na2O. The linear thermal expansion coefficients range from 658 to 1054×10−8, and the relationship between thermal expansion and composition is linear. The transformation and transition points were determined.
