Abstract

PROCEDE ET APPAREIL DE MESURE DU POTENTIEL D'OXYDO-REDUCTION DE MASSES FONDUES A CONDUCTIBILITE IONIQUE TELLES QUE DES VERRES AU SILICATE DE SODIUM ET A LA CHAUX SODEE, DANS LESQUELS UNE ELECTRODE DE REFERENCE ET UNE ELECTRODE INDICATRICE 11 SONT ACCOUPLEES PAR UN POTENTIOMETRE ET INSEREES DANS LA MASSE FONDUE, LES ELECTRODES DE REFERENCE ET INDICATRICE ETANT SEPAREES D'UNE DISTANCE D'AU MOINS 3MM ET L'ELECTRODE INDICATRICE ETANT ISOLEE A SON POINT D'ENTREE DANS LA MASSE FONDUE POUR EVITER LA FORMATION D'UNE INTERFACE A TROIS PHASES ENTRE LA MASSE FONDUE, L'ELECTRODE ET L'ATMOSPHERE GAZEUSE SITUEE AU-DESSUS DE LA MASSE FONDUE. LE PROCEDE ET L'APPAREIL EVITENT LE PROBLEME POSE PAR LE TRANSFERT DE L'OXYGENE PAR L'ELECTROLYTE SOLIDE DE L'ELECTRODE DE REFERENCE QUI EMPECHAIT LES SONDES A OXYGENE ANTERIEUREMENT CONNUES DE MESURER LE POTENTIEL D'OXYDO-REDUCTION DE MASSES FONDUES A CONDUCTIBILITE IONIQUE.
