METHOD FOR PRODUCING A TUBE CONSISTING OF DOPED QUARTZ GLASS, TUBULAR SEMIFINISHED PRODUCT CONSISTING OF POROUS QUARTZ GLASS, QUARTZ GLASS TUBE PRODUCED THEREFROM AND USE OF THE SAME |
摘要 |
According to a known method for producing a tube consisting of doped quartz glass, the starting components are fed to a deposition burner, particles containing SiO2 and GeO2 are formed, and are deposited on a mandrel rotating about its longitudinal axis, forming a porous layer of soot. Based on said method, the aim of the invention is to ensure that the doping agent is distributed over the tube wall in a radially homogeneous manner. In order to achieve this, an outer compression area (3) having a higher density is generated in the outer area of the layer of soot, and surrounds an inner area (2) of the layer of soot, said inner area having a lower density. A tubular semifinished product consisting of porous quartz glass containing GeO2, which can be subjected to dehydration treatment without significantly changing the predefined distribution of doping agent over the tube wall, is characterised in that the area of the outer wall of the tube is provided with an outer compression area (3) having a higher density and surrounding an inner area (2) having a smaller density. |
