Apparatus for synthetic quartz glass blanks production by silica deposition has a simplified and flexible conveyor (e.g. of polyfluoroalkoxy) between the raw material container and the deposition burner

摘要

Connector to convey raw materials in contact with heat between heater-containing container (10) for the hydrolyzable silicon- containing raw materials and the deposition burner (18) for producing silica particles for production of synthetic quartz glass blanks is formed of flexible inner tube (1) with the heating agent included in a flexible outer tube (2) and there being a gap (5) for a temperable fluid (7) between tubes (1) and (2).
