Abstract

PURPOSE:To obtain a doped quartz glass rod having a desired diameter and length and a uniform dope amt. distribution in the diametrical direction by subjecting gases spouted from a concentric circular nozzle to flame oxidation decomposition in a tubular combustion chamber so that turbulent diffusion combustion is carried out. CONSTITUTION:Feed gas 3, i.e. silicon cpd. gas or mixed gas of silicon cpd. gas and inert gas, and oxygen gas 5 are spouted from concentric circular nozzle 10 with inert gas 4 in-between and subjected to flame oxidation decomposition while carrying out diffusion combustion. The resulting fine powder glass is deposited to produce a doped quartz glass rod. In this method gases 3, 4, 5 spouted from nozzle 10 are subjected to flame oxidation decomposition in tubular combustion chamber 2 so that turbulent diffusion combustion is carried out. In order to stably hold the turbulent diffusion combustion, it is desirable to adjust the flow rate of all of the gases to 70cm/sec or more and that of oxygen gas 5-50cm/sec or more.
