摘要
Floated lithium - aluminosilicate - flat glass with a high temperature resistance, the chemically and thermally prestressed, and the without the use of the usual fining agent arsenic - and / or antimony oxide is refined, with a composition which, in wt.% based on the total composition, contains the following main constituents:
Li2O2,5-6,0Σ na2O + k2O 4B2O30- 4Al2O315-30Sio255-75Σ tio2 + Zro2≤ 1,5 (around the crystallization of undesired high quartz - and / or keatite mixed crystals - to avoid)
