Abstract

PURPOSE:To make possible obtaining a large volume of glass stock material through the use of vapor phase chemical reaction and at high efficiency by vitrifying soot while feeding a rare gas, setting a reaction tube perpendicular and filling the reaction tube with the glass which melts and droops.
