    摘要: A method for producing a glass preform for an optical fiber by an outside vapor-phase deposition method, which comprises forming fine glass particles by jetting gaseous glass raw material and fuel gas from a first burner to deposit the particles on a seed rod to form a soot rod at such a temperature that a specific bulk density of the soot rod being formed is low and subsequently heating the soot rod by a second burner so as to increase the bulk density of the soot and then sintering the soot rod to obtain a transparent glass preform for an optical fiber, by which method, a highly pure glass preform is produced in a good deposition yield without cracking.

    摘要: A process is disclosed for the removal of water and water derived impurities, e.g. OH.sup.-, substitutionally or interstitially incorporated in the structure of crystalline and amorphous materials, more specifically, in metal oxides, e.g. fused silica or aluminum oxide, wherein the material is exposed in powdered form to a gaseous mixture of halogen and carbon monoxide at a predetermined elevated temperature. The mixture of halogen and carbon monoxide reacts to cause the water and OH.sup.- ion concentration in the processed material to be reduced to an extremely low level. Materials purified by the process can be used to produce optical fibers and laser windows of excellent mechanical, thermal and optical properties.

    摘要: An improved method of preparing optical fiber preforms and optical fibers by so called rod-in-tube method, wherein before collapsing a tube to heat-adhere to a rod, a specific glass surface treating agent and oxygen gas are flowed through the clearance between the rod and the tube maintained at a high temperature, whereby an optical fiber preform free from imperfections at the interface between the rod and the tube can be produced so as to give optical fibers of low-loss. As the above glass surface treating agent, those materials are employed which satisfy the following criteria: (i) the hydrogen content thereof being not more than about 1% by weight, and (ii) the substances, produced therefrom in the presence of oxygen gas at a high temperature, having a boiling point or sublimation point of not more than the temperature required for collapsing the tube.
