| titleOfInvention | Manufacturing method and manufacturing apparatus for glass base material |
| abstract | An object of the present invention is to provide a method and an apparatus for manufacturing a glass base material capable of making the thickness of a glass layer uniform in a longitudinal direction in an MCVD method. A glass material gas is fed into a quartz tube, and the quartz tube is rotated by a first heating source from the outside while rotating the quartz tube around its central axis, and glass fine particles are introduced into the quartz tube. After the glass fine particle layer 35 is formed by deposition, when the glass fine particle layer 35 is made transparent, the glass layer 13 is made transparent using the second heating source 12. The heating range of the first heating source 11 is set smaller than that of the second heating source 12 and the traverse speed is set smaller. [Selection diagram] Fig. 1 |
