Abstract
PROCEDIMIENTO PARA LA REDUCCION DE LOS RADICALES OXIDRILOS EN PREFORMAS PARA FIBRAS OPTICAS. CONSISTE EN INTERCAMBIAR EL HIDROGENO DE LOS OXIDRILOS PRESENTES EN UN TUBO DE SOPORTE DE VIDRIO DE SILICE (6) CON DEUTERIO. LA REDUCCION SE LLEVA A CABO EN EL INTERIOR DE UN HORNO DE MUFLA (5) E INTRODUCIENDO EL DEUTERIO CONTENIDO EN UN DEPOSITO (1). EN UNA PRIMERA FASE SE MANTIENE LA TEMPERATURA INTERIOR DEL HORNO ENTRE 100 Y 200GC DURANTE UNAS HORAS Y EN UNA SEGUNDA FASE SE ELEVA LA TEMPERATURA HASTA 500GC.
