Abstract |
AB |
[EN] The present disclosure relates to an alkali-aluminosilicate glass which contains between 47.5 and 55 wt.% SiO2, between 21 and 27.5% Al2O3; and between 12 and 16 wt.% Na2O. The molar ratio of Al2O3 and Na2O amounts to between 1:0.9 and 1:1.2. This glass is characterized by high hardness and high surface strengths after its chemical toughening, whereby the resulting extremely high scratch resistance favors its use as a display glass. A further preferred feature of this glass is its much lower viscosity for this group of glasses. |
