Abstract
PURPOSE:To produce the title material rendering the sectional structure of optical fiber stable with high productivity by using a plasma flame made in a rotatable reaction tube; specifying the linear velocity of gases flowing through the tube; and regulating the press. inside the tube to make the press. constant. CONSTITUTION:By applying voltage to high frequency induction coils 3 from high frequency power source 4 plasma flame 8 is made in reaction tube 2 which is simultaneously rotatable and movable back and forth relatively to coils 3. Raw gases such as SiCl4, GeCl4 and O2 are introduced into tube 2 from raw material feeder 1 and reacted with flame 8 under the following conditions to form a glass film of SiO2, etc. on the inner wall of tube 2: the linear velocity of the gases flowing through tube 2 is controlled to above 10 m/min, and press. regulation valve 5 of press. regulation mechanism 6 in tube 2 is regulated to hold the press. inside tube 2 constant.
