Abstract

PURPOSE: To provide inexpensive acid leachable glass with high durability useful for manufacturing a flexible optical fiber by using a specified amount of SiO2, B2O3, BaO and Na2O, K2O or Li2O.
CONSTITUTION: This glass has a composition consisting of, by mole, 9.0%<SiO2< 15.0%, 38.0%<B2O3<57.0%, 10.0%<BaO<27.0% and 5.0%<(one or more among Na2O, K2O and Li2O)<19.0%. In case of ≤9.0% SiO2 and ≥15.0% SiO2 in said composition sufficient water resistance and sufficient acid leachability are not obtd., respectively. In case of ≤38.0% B2O3 it is difficult to obtain sufficient acid leachability, and in case of ≥57.0% B2O3 sufficient water resistance is not obtd. When the BaO content is ≤10.0%, the viscosity of the glass is reduced excessively during the heat drawing of an optical fiber strand, and when the BaO content is ≥27.0%, the viscosity is excessively dependent on the temp.
