Abstract

Durability of glass, or its resistance to corrosion, as a function of glass composition, surface state, and environmental conditions, has been discussed extensively in context with concepts for chemical reaction mechanisms and changes in surface structure involved in corrosion processes. In practical terms, durability and corrosion of silicate glasses are mainly affected by surface composition, and conditions during manufacturing, fabrication, storage and service. Deterioration of surface properties due to corrosion may range from light haze or stain to severe damage such as iridescence or opacity. Methods for improving durability and reducing corrosion include chemical modification of surface layers by ion-implantation, ion-exchange, or chemical reaction, application of protective materials, and deposition of durable oxide films on the glass surface.
