Abstract

ία μέθοδος δια τον καθαρισμό οξειδίου του αργιλίου, ήτις περιλαμβάνει την πύρωσιν οξειδίου του αργιλίου περιέχοντος σόδαν ομού με ένα συλλιπαντικόν παράγοντα όστις παράγει κατ'ουσίαν ανακρυσταλλώμενον οξείδιον του αργιλίου και όστις επίσης αντιδρά μετά της σόδας ήτις περιέχεται είς το ρηθέν οξείδιον του αργιλίου πρός σχηματισμόν ενός διαλυτού άλατος του νατρίου, και την υποβολήν του παραγομένου ανακρυσταλλωμένου οξειδίου του αργιλλίου είς έκπλυσιν δια καθαρού ύδατος ή ενός αραιού υδατικού διαλύματος ενός οξέος ή ενός αλκάλεος.A method for the purification of aluminum oxide, which involves the combustion of aluminum oxide containing soda together with a coolant which produces substantially recrystallized aluminum oxide and which also reacts with the soda to form an oxide soluble sodium salt, and subjecting the produced recrystallized aluminum oxide to rinsing with pure water or a dilute aqueous solution of an acid or alkali.
