Abstract

PURPOSE:To obtain a chalcogenide glass for an optical fiber with low loss, by heat-treating a raw material for forming the chalcogenide glass in the stream of a gaseous halide or gaseous halogen, and melting and vitrifying the heat-treated raw material. CONSTITUTION:A Ge-S chalcogenide glass is dehydrated with S2Cl2 as a treating agent 3. The S2Cl2 is introduced into a saturator container 2, gasified by blowing a transporting gas from a transporting gas introductory port 1 into the saturator container 2, and then led to a quartz glass tube 8 provided in a quartz glass cover 5. A powdery sulfur and germanium in the form of an ingot as a raw material 7 for forming glass are introduced into the quartz glass tube 8 and heated by a heater 6, and the gasified S2Cl2 is made to flow while melting the sulfur. The S2Cl absorbs water and is decomposed in the heating part to give a gas, e.g. HCl or SO2, and the unreacted S2Cl2, which are expelled from a duct 9. The raw material 7 after the treatment is sealed up in the quartz tube 8 under reduced pressure, molten and vitrified to give a chalocgenide glass for an optical fiber.
