HIGH RARE EARTH CONTENT SODA LIME COMPATIBLE GLASS

Abstract:

An example glass composition comprises rare earth content (e.g., rare earth oxides, elements, and/or ions) of from about 0.5 mol % to about 20 mol %. The glass composition may have a liquidus temperature that is within a specified range, a softening point that is within a specified range, a working point that is within a specified range, and/or a coefficient of thermal expansion (CTE) that is within a specified range.
