Abstract
PURPOSE:To stabilize the compsn. of glass-forming oxide soot and to enhance the yield thereof by introducing glass raw material chlorides, O2 gas and steam into a reaction tube and by heating them to form the oxide soot in the tube. CONSTITUTION:Oxygen gas as carrier gas is introduced into evaporator 23 to support POCl3, and GeCl4 is also supported on oxygen gas in evaporator 26. Valve 29 for feeding oxygen gas to evaporator 27 contg. GaCl3 is being closed. Oxygen gas is introduced into evaporator 33 to support steam. The POCl3 and GeCl4 undergo hydrolysis in reaction tube 30 heated to a high temp. with heating furnaces 36, forming compound oxide soot of GeP2O7, which is gathered in container 37. Next tube 30 and container 37 are changed for new ones, and using evaporator 27 in place of evaporator 26 compound oxide soot of GaPO4 is gathered similarly. The soots are weighed in a proper ratio, mixed, heated in a double quartz crucible, and converted into glass for a light transmission line.
