FIELD: production of fiber-optic light conduits.
SUBSTANCE: proposed method includes settling of glass-forming oxides on seed bead by delivery of vapor-gas mixture of halogenides of respective elements to flame of burner which moves along bead. Vapor-gas mixture is fed to circular clearance between seed bead and tube located coaxially relative to it and mounted together with burner on movable support of machine. Tube moves in synchronism with burner and vapor-gas mixture is fed at angle of 10-60° to axis of seed bead. Width of circular clearance is set between 0.8D and 1.5D, where D is diameter of jet of vapor-gas mixture at circular clearance inlet; length of tube is set between 10h and 30h, where h is width of circular clearance.
EFFECT: enhanced efficiency of settling of aerosol oxides on blank of fiber-optic light conduit.
