Abstract

The invention discloses a composition for preparing glass, a glass article and a use thereof, and a glass article made from the composition. The glass article is preferably a glass substrate made from a composition with an M value of from about 1 to about 10 as calculated by the empirical equation: M=0.13×wt (B2O3)×wt (B2O3)+0.42×wt (CaO)+0.55×wt (MgO)+0.75×wt (SrO)−0.05×wt (Al2O3)×wt (Al2O3). A use of the glass article (especially the glass substrate) for manufacturing a display device is disclosed herein, wherein the glass article has better properties, such as lowered content of solid inclusions and gas inclusions, lowered thickness range and lowered warpage.
