초록 ▼

A method for fabricating a large-sized primary treated quartz glass tube by perforating a cylindrical quartz glass mother material by a hot carbon drill press-in-process followed by etching and washing. The large-sized primary treated quartz glass tube is converted to a large-sized quartz glass preform by combining it with a core glass rod for an optical fiber. Another embodiment is a method for fabricating a large-sized quartz glass tube by heating, hot drawing or hot drawing under pressure using a tool-free drawing method under control of an inside pressure of the large-sized primary treated quartz glass tube at a temperature ranging from 1600.degree. C. to 3000.degree. C. to satisfy a specific equation.

[ We claim:] [1.] A method for manufacturing a large-sized primary treated quartz glass tube,said quartz glass tube having:(i) an outer diameter in a range from 50 mm.phi. to 300 mm.phi.(ii) an outer to inner diameter ratio falling in a range from 1.1 to 7;(iii) a wall thickness of 10 mm or more;(iv) a wall thickness error of 2% or less; and(v) a roughness of an inner surface of 20 .mu.m or less rein the method comprises the steps of:(a) perforating a cylindrical quartz glass mother material by a hot carbon drill press-in process;(b) grinding, abrading and finishing outer surfaces of the perforated mother material;(c) etching the inner and outer surfaces of the perforated mother material with hydrofluoric acid to obtain a processed mother material; and(d) washing said processed mother material. [3.] A method for fabricating a large-scale quartz glass preform which comprises the steps of,(a) preparing a large-sized quartz glass tube having(1) an outer diameter in a range from 50 mm.phi. to 300 mm.phi.(2) an outer to inner diameter ratio in a range from 1.1 to 7,(3) a wall thickness of 10 mm or more,(4) a wall thickness error of 2% or less, and(5) a roughness of an inner surface being 20 .mu.m or less; and(b) combining a core glass rod for an optical fiber integrally with the large-sized quartz glass tube wherein the large-sized quartz glass tube is a large-sized heat-treated quartz glass tube obtained by the steps comprising heating, hot drawing or hot drawing under pressure a large-sized primary treated quartz glass tube using a tool-free drawing method under control of an inside pressure thereof in a temperature range from 1600.degree. C. to 3000.degree. C. so as to satisfy the following equation: EQU (D.sub.o /D.sub.i)/(d.sub.o /d.sub.i)=1.0.about.1.5 re D.sub.o and D.sub.i respectively represent the outer and inner diameters of the primary treated quartz glass tube; andd.sub.o and d.sub.i respectively represent the outer and inner diameters of the large-sized heat-treated quartz glass tube obtained from the primary treated quartz glass tube.
