Chemical Durability Improvement and Static Fatigue of Glasses.
Abstract
Chemical durability of glass can be improved by applying a coating on the surface. It was also found that an addition of a minor quantity of calcium to the alkaline solution drastically improves the durability of silica glass. It was confirmed that calcium produces a film on the glass surface and protects the glass. A systematic study was made on the effects of all alkaline earth elements to see whether a similar phenomenon exists. All the alkaline earth elements were found to produce films, to a varied degree, on silica glass surface in alkaline solution. In addition, extensive crack growth was observed in the case of heavy alkaline earth elements such as Ba and Sr.
