Abstract

ις μίαν μέθοδον δια την κατασκευήν υδροξειδίου του αργιλίου περιλαμβάνουσαν την διάσπασιν ενός υδατικού διαλύματος αργιλικού νατρίου δι' αναδεύσεως παρουσία μιας επιβοηθητικής ύλης διασπειρωμένης εντός του εν λόγω διαλύματος, η τελειοποίησις ήτις συνίσταται εις το να εισάγη τις κατά τρόον συνεχή, εντός του ρηθέντος διαλύματος, μίαν επιβοηθητικήν ύλην απαρτιζομένην εκ μίγματος τριϋορίτου της αλουμίνας με εν διάλυμα προερχόμενον εκ μερικής τουλάχιστον διασπάσεως του διαλύματος του αργιλικού νατρίου αφετηρίας του εν λόγω μίγματος περιέχοντος τουλάχιστον 40% κατά βάρος Al2U3. In one method for making aluminum hydroxide comprising decomposing an aqueous solution of sodium aluminate by stirring in the presence of an adjuvant dispersed in said solution, the refinement is to introduce the diluent continuously into the solution. Auxiliary material consisting of a mixture of alumina triorite with a solution resulting from at least partial decomposition of the starting sodium aluminate solution of said mixture containing at least 40% by weight Al2U3.
