Abstract

PURPOSE:To produce the title material of high purity by introducing carrier gas supporting a specified chloride into pure water; reacting them; and heat calcining the reaction product after removing unreacted pure water and hydrogen chloride gas. CONSTITUTION:Evaporator 12 housing one or more kinds of chlorides selected from GeCl4, SiCl4 and GeCl3 is set in water bath 14 heated with heater 13, and feed valve 11 is opened to introduce carrier gas into evaporator 12, thereby supporting the chlorides on the gas. This supporting gas is introduced into evaporator 16 housing pure water to react the chlorides with the water. Next, valves 11, 15 are closed, valve 17 is opened, and oil bath 19 is heated with heater 18 to evaporate hydrogen chloride and unreacted pure water in evaporator 16. After slow cooling, the residual reaction product is shifted to another container and heat calcined to obtain a glass raw material oxide for a light transmission line.
