摘要
A glass composition and its use for producing glass tubes is provided. The glass tubes having the provided composition are particularly suitable for the outer tubes of fluorescent lamps in the case of which a phosphor layer is baked at temperatures of up to 700° C. The tubes composed of the glass of the provided composition have a lower tendency to deform or stick together when processed at high temperatures. To obtain the observed effects, the molar ratio of Na2O/(Na2O+K2O), inter alia, is greater than 0.4 and not more than 0.72.
