Summary (abstract)

This paper describes the electron microscope morphology of gels of aluminium hydroxide and of aluminium oxide monohydrate Böhmite and the transformations which occur at room temperature during the aging of C-alpha gel prepared from ammonium alum. A mechanism for the morphological transformations during the aging of C-alpha gel and for the formation of somatoids is suggested.

Zusammenfassung

In dieser Arbeit werden elektronenmikroskopisch die morphologischen Eigenschaften von Gelen aus Aluminiumhydroxyd und Aluminiumoxydmonohydrat Böhmit untersucht und die Änderungen verfolgt, die bei Zimmertemperatur beim Altern von C-alpha-Gel, hergestellt aus Ammoniumalaun, eintreten. Es werden Betrachtungen über den Alterungsmechanismus und die Bildung sogenannter Somatoide (Bezeichnung von Kohlschütter) angestellt.
