Abstract

Procedimiento perfeccionado para la electrolisis de alúmina, especialmente aplicable a la fabricación del aluminio por electrolisis ignea de la alúmina, caracterizado porque dicha alúmina se disuelve en un baño criolitario constituido por una mezcla de criolita sódica (Al F elevado a 3, 3 NaF), de criolita lítica (Al F elevado a 3, 3 Lif) y de criolita potásica (Al F elevado a 3, 3KF).
