Downdraw Extrusion of ULE(TM) Glass.

Abstract

This report documents an experiment to determine whether it is possible to extrude Ultra Low Expansion (ULE) silica glass. A heat cycle experiment was performed which demonstrated that the material could withstand the time/temperature cycle required in the appropriate chemical environments. Extrusion apparatus was then assembled, configured and tested. Two runs were made in which ULE was extruded. Although the results showed much scatter of the data, the mean properties of the extruded material were the same as for the control material, which suggests that with more process optimization, extrusion of ULE in sufficiently high quality for mirrors should be possible.
