Abstract

LA DISOCIACION PREMATURA DEL AGENTE DE AFINADO SE EVITA, EN UNA OPERACION DE FUSION DE VIDRIO, MEDIANTE EL CONTROL DEL ESTADO FINAL DE REDOX EN EL VIDRIO, POR LA INICIACION DEL PROCESO DE FUNDIDO BAJO CONDICIONES RELATIVAS DE OXIDACION Y POSTERIORMENTE ALTERANDO LAS CONDICIONES DE REDOX PARA HACER EL VIDRIO MAS REDUCTOR. EL VIDRIO QUE ESTA MAS REDUCIDO DE LO NORMAL, PUEDE, DE ESTA MANERA, PRODUCIRSE SIN SACRIFICAR EL ADECUADO AFINADO DEL VIDRIO. PARA UN NIVEL REDOX DADO, SE NECESITA UTILIZAR MENOS AGENTE DE AFINADO, BAJANDO, DE ESTA MANERA, LAS EMISIONES DE LA OPERACION DE FUNDIDO, DADO QUE LA DISLOCACION DEL AGENTE DE AFINADO SE RETRASA HASTA UNA ETAPA POSTERIOR DEL PROCESO DONDE LAS CONDICIONES REDOX CAMBIEN.
