Abstract

Beansprucht werden polykristalline Korundfasern bestehend im Wesentlichen aus Korund und einem Oxid von Elementen der I. oder II. Hauptgruppe des Periodensystems, wobei die Kristallite dieser Korundfasern folgende Korngrößenverteilung aufweisen: 0 bis 0,15 Mikrometer (34 %), 0,15 bis 0,29 Mikrometer (55 %) und 0,29 bis 0,43 Mikrometer (11 %). Diese Korundfasern werden hergestellt, indem man Aluminiumchlorohydrat mit Keimen und einem Oxidbildner von Elementen der I. und Il Hauptgruppe des Periodensystems versetzt, ein wasserlösliches Polymer zugibt, daraus Fasern spinnt und diese Fasern bei Temperaturen von über 1100°C kalziniert.
