Abstract

The invention discloses an anti-magnetic glass system for the preparation of a single-mode magneto-optic glass fiber. The system is based on a TeO2 and PbO glass network body, and through the stable B2O3 and SiO2 glass structure, the glass performance parameter is improved. The glass components of a core and a shell refer to (58.8-60 mol%)TeO2-(39.2-40 mol%)PbO-(0-2 mol%)B2O3 and (56-57 mol%)TeO2-(36-38 mol%)PbO-(0-4 mol%)B2O3-(0-3 mol%)SiO2. The glass is prepared through a melt quenching process at 900-1000 DEG C. The Faraday coefficient (0.2-0.25min / Oe.cm) of the system is large, the systemhas no temperature dependence, visible light and infrared light transmittance is larger than 70%, the thermal stability is larger than 100 DEG C, and the system meets the matching requirements of magneto-optic glass fiber cores and shell glass for the linear thermal expansion coefficient, the refractive index and the glass transition temperature.

Description
