Abstract
PURPOSE:To obtain a high purity glass pipe of low OH group content by forming a porous glass body at a part where a movable support rod contacts with a fixed support rod, moving the movable support rod in proportion to the formation of the body, and making the body transparent in a heating furnace. CONSTITUTION:Glass fine particles are allowed to spout from burner 8 toward both surfaces of rotating movable support rod 6 and fixed support rod 7 together with a flame to form porous glass body 9. When body 9 grows to a predetermined thickness, rod 6 is moved while rotating. As a result, said body 9 shifts with a hollow part left, and it is converted into transparent glass pipe 11 by heating with heating furnace 10 placed in the rod moving direction. At this time, body 9 is shrunken. This transparent vitrification is carried out in the presence of a dehydrating agent such as Cl2 or SOCl2 to remove OH groups in the quartz glass pipe.
