<P>PROBLEM TO BE SOLVED: To provide a method which uses a raw material supplied in a stable composition and can be used for easily producing titania-silica glass of homogeneous composition. <P>SOLUTION: The method for producing the titania-silica glass comprises separately supplying a gas prepared by gasifying a liquid raw material of a silica source or a gas prepared by gasifying a liquid raw material of a titania source from either one of a first introduction pipe which is a center of a multitubular pipe of a concentric multiple pipe burner, a second introduction pipe which flanks with the periphery of the first introduction pipe, and a third introduction pipe which flanks with the periphery of the second introduction pipe, hydrolyzing the gas in oxyhydrogen flame of the burner, depositing glass particles on a target, and then subjecting the glass particles to a heat vitrifying treatment. <P>COPYRIGHT: (C)2008,JPO&INPIT |
