Borosilicate Glass with Low Brittleness and High Intrinsic Strength, the Production Thereof, and the Use Thereof

An alkali borosilicate glass is provided that includes: SiO2 70-86 wt % Al2O3 0-5 wt % B2O3 9.0-25 wt % Na2O 0.5-5.0 wt % K2O 0-1.0 wt %, and Li2O 0-1.0 wt %. The proportions of the components are chosen in such a way that the weighted crosslinking index, that is, the mean number n of constraints pe...

Zusammenfassung:	An alkali borosilicate glass is provided that includes: SiO2 70-86 wt % Al2O3 0-5 wt % B2O3 9.0-25 wt % Na2O 0.5-5.0 wt % K2O 0-1.0 wt %, and Li2O 0-1.0 wt %. The proportions of the components are chosen in such a way that the weighted crosslinking index, that is, the mean number n of constraints per atom has a value greater than 2.9.
