LAMINATE GLASS CERAMIC ARTICLES WITH UV-AND NIR-BLOCKING CHARACTERISTICS AND METHODS OF MAKING THE SAME

Abstract:

A laminate glass-ceramic article is provided that includes: a core glass layer having a first coefficient of thermal expansion (CTE); and a plurality of clad glass-ceramic layers, each having a CTE that is lower than or equal to the first CTE of the core glass layer. A first of the clad glass-ceramic layers is laminated to a first surface of core glass layer and a second of the clad glass-ceramic layers is laminated to a second surface of the core glass layer. Further, a total thickness of the plurality of clad glass-ceramic layers is from about 0.05 mm to about 0.5 mm. In addition, each of the glass-ceramic layers includes: an alumino-boro-silicate glass, 0 mol %.ltoreq.MoO.sub.3.ltoreq.15 mol %, and 0 mol %.ltoreq.WO.sub.3.ltoreq.15 mol %, the WO.sub.3 (mol %) plus the MoO.sub.3 (mol %) is from 0.7 mol % to 19 mol %.
