| Abstract: | A study with soda-lime glass rods showed that modulus of rupture values can be increased from approximately 124 × 106 Pa (18 ksi) to 276 × 106 Pa (40 ksi) by heat treatment. Dipping the rods into diethyldichlorosilane prior to heating at 593°C (1100°F) or exposing hot glass to the silane vapor following heat treatment increased strength an additional 30% over the average strength obtained by heating only at this temperature. Similar treatment with phenyltrichlorosilane or diethyldichlorosilane did not give strengths statistically higher than those obtained by heating alone. |
