Abstract

έθοδος δια την παρασκευή ανύδρου οξειδίου του αργιλλίου έξ υδροξειδίου του αργιλλίου κατά την αρχήντης στροβιλιζομεης στιβάδος κατά την οποίαν αι στερεαί ύλαι ομού μετά των αερίων εξάγονται έκ του άνω μέρους της φρεατοειδούς καμίνου, έν μέρος της θερμότητος προσάγεται εντός του στροβιλιζομεου λίκνου άνωθεν της εσχάρας και αι είς το ανώτερον μέροςτης φερατοειδούς καμίνου εξερχόμεναι στερεαί ύλαιδιαχωρίζονται εντός ενός κυκλώνος ανακυκλώσεως από του αερίου κα ιεπαναρποσάγονται, μερικώς τουλάχιστιον εντός του στροβιλιζομεου λίκνου, χαρακτηριζομένη έκ του ότι το υδροξείδιον του αργιλλίου προαφυδατούται κα ιαπαλλάσσεται του χημικώς ηνωμένου ύδατος εντο ενός πολυβαθμίου εναλλακτήρος αιωρήσεως (3,4,5,6,7).
