摘要：
Glass compositions are disclosed for use in producing light transmitting glass fibers composed of a central core glass surrounded by an outer cladding glass. The core glasses have the following range of proportions (by weight): SiO2, 23-41%; A12O3, 7-10%; B2O3, 2.5-11%; K2O, up to 10%; BaO, 34-59%; Sb2O3, up to 0.05%, preferably 0.01 to 0.05%. The cladding glasses have the following range of proportions (by weight): SiO2, 61-65%; A12O3, 4-6%; CaO, up to 3%; MgO, 0.90-4%; B2O3, 12-16%; Na2O, 7-12%; Li2O, up to 4%; F2, up to 3%; SeO2 up to 0.004%, preferably 0.002 to 0.004%.
