Abstract

Interlayer K was extracted with sodium tetraphenylboron solution from a powdered sericite heated to the temperature of dehydroxylation and quenched to room temperature. By this procedure, sericite of the 2M1 type was changed to an interstratified mineral. The X-ray diffraction properties of this interstratified mineral are similar to “rectorite”.

Résumé

Résumé

Le potassium interfeuillet a été extrait, par une solution de tétraphénylborate de sodium, d’une séricite en poudre chauffée à la température de déshydroxylation et ramenée à la température ambiante. Par cette méthode, la séricite du type 2M1 a été transformée en un minéral interstratifié. Les propriétés de ce minéral interstratifié en diffraction des rayons X sont semblables à celles de la “rectorite”.

Kurzreferat

Kurzreferat

Zwischenschicht-K wurde mittels Natrium Tetraphenyl boronlösung aus einem Serizitpulver, das auf die Dehydroxylierungstemperatur erhitzt und dann auf Zimmertemperatur abgeschreckt worden war, extrahiert. Durch diesen Vorgang wurde Serizit des 2M1 Typs in ein zwischengeschichtetes Mineral verwandelt. Die Röntgenbeugungseigenschaften dieses zwischengeschichteten Minerals sind ähnlich denen von ‘Rectorit’.

Резюме

Резюме

Из размолотого серицита нагретого до температуры дегидроксилизации и охлажденного до комнатной температуры раствором тетрафенилборного натрия экстрагировался промежуточный слой К. Этой процедурой серицит типа 2М1 был преобразован в слоистый минерал. Рентгенографическое исследование показало, что диффракционная картина этого слоистого минерала такая же как у ректорита.
