Abstract

PURPOSE:To make the thickness of a deposited glass layer uniform in the longitudinal direction by setting a cooling means for the outer wall of a reaction tube in the vicinity of a burner heating the outer wall of the tube so that the cooling means is moved in the moving direction of the burner in synchronism with the burner. CONSTITUTION:Ar carrying SiCl4 and GeCl4 and gaseous O2 introduced into a reaction tube 1 from the introducing end 2, and a burner 3, a cooling nozzle 12 and an electrically heating furnace 13 are moved from the end 2 to the gas exhausting end 5. Since the outer wall of the tube 1 is cooled with a refrigerant from the nozzle 12, most of oxide soot 14 produced at a high temp. in the vicinity of the burner 3 is stuck to the inner wall of the tube 1 within a small region in the moving direction of the burner 3. The sticking of the residual soot to the inner wall of the tube 1 is avoided since the wall is heated with the furnace 13 adjacent to the nozzle 12. Accordingly, deposition with a trail left in the moving direction of the burner 3 is prevented and a glass layer having a uniform thickness is obtd.
