<p>In a known method for producing a quartz glass body, glass starting material and combustible gas are supplied to a deposition burner, SiO<SUB>2</SUB> particles are formed therefrom, and said particles are deposited in layers on a carrier with formation of an SiO<SUB>2</SUB> blank. Starting therefrom, to indicate a reproducible method for producing a high-purity homogeneous quartz glass body, it is suggested according to the invention that a deposition burner should be used which consists at least in part of graphite. An apparatus according to the invention for producing a quartz glass body comprises a deposition burner including a burner head having a burner mouth, in which burner head a plurality of media supply lines extend for supplying glass starting material and combustible gas, said lines terminating at the burner mouth in the form of nozzle openings. To manufacture the deposition burner with narrow manufacturing tolerances at low costs and to prevent the risk of contamination at the same time, it is suggested according to the invention that the burner head should consist at least in part of graphite.</p> |
