Process for producing a tubular semifinished product from fluorine-doped quartz glass |
| abstract |
In order to improve generally known processes for the production of a tubular semifinished product from fluorine-doped quartz in such a way that the production of tubular quartz products from fluorine-doped quartz glass with high-quality inner bore is made possible with as little effort as possible for their production or processing, a method is proposed according to the invention which comprises the following method steps In a deposition process, SiO 2 particles are formed by means of plasma torches and in the presence of fluorine and on the cylindrical surface of the substrate tube rotating about its longitudinal axis to form a mother tube of fluorine doped Quartz glass is deposited in layers and (c) in a Elongierprozess the nut tube is elongated to the tubular semi-finished product. |
