摘要

New, PbO-free glasses for cathode ray tubes are composed of (in % by weight) 50-52 SiO.sub.2 ; 0-3 Al.sub.2 O.sub.3 ; 1-1.7 Li.sub.2 O; 6.5-10. 7 Na.sub.2 O; 0-4.5 K.sub.2 O; 0.4-1.4 F; 0-0.5 TiO.sub.2 ; 0. 2-1.2 CeO. sub.2 ; 0-5 ZnO; 0-7.0 BaO; 15-22 SrO; and 6.3-10.3 ZrO.sub.2, and are characterized by a high protective effect against X-rays while having at the same time good resistance to acid and stability to radiation.
