Abstract :
Hydrogen-induced loss in the hydroxyl absorption band is found to be reduced by accelerating the drawing speed and by depressing the furnace temperature. By analysing the thermodynamic behaviour of defects during the drawing process, sites reactive with hydrogen causing this loss are shown to be drawing-induced defects.
