Abstract

Several illites and a mixed-layer illite-montmorillonite developed fractures in some particles during progressive removal of interlayer potassium by solutions containing sodium tetraphenylboron. The appearance of the splinters in bundles, some connected to incompletely broken plates, suggests the process is related to the differential release of stresses known to exist as a consequence of octahedral-tetrahedral misfit. The formation of splinters produces additional surface area for ion removal and may influence the rate of vermiculite development.

Résumé

Résumé

Plusieurs illites et un interstratifié illite-montmorillonite montrent le développement de fractures dans certaines particules au cours de l’élimination progressive du potassium interfeuillet par des solutions contenant du tétraphénylborate de sodium. L’apparition d’éclats en gerbes, certains d’entre eux étant attachés à des plaques incomplètement brisées, suggère que le phénomène est relié à la disparition différentielle des contraintes provenant des défauts de raccordement entre couches octaédriques et tétraédriques. La formation des éclats produit une surface supplémentaire pour l’élimination des ions et peut influencer la vitesse du développement de la vermiculite.

Kurzreferat

Kurzreferat

Mehrere Illite und ein gemischtschichtiger Illit-Montmorillonit entwickelten Risse in einigen Teilchen während der fortschreitenden Entfernung von Zwischenschichtkalium durch Lösungen, die Natrium-Tetraphenylbor enthielten. Das Auftreten von Splittern in Bündeln, manche mit unvollständig gebrochenen Platten verbunden, deutet daraufhin, dass der Vorgang mit der unterschiedlichen Freigabe von Spannungen in Beziehung steht, die bekanntlich als Folge oktaedrischem Nichtpassens bestehen. Die Bildung von Splittern führt zu zusätzlicher Oberfläche für die Entfernung von Ionen und kann die Geschwindigkeit einer Entwicklung von Vermiculit beeinflussen.

Резюме

Резюме

Во время прогрессивного удаления межслоевого калия растворами содержащими тетра- финилборный натрий в частицах иллита и в частицах смешанных слоев монтмориллонита-иллита появились трещины. Появление осколков в срастаниях, приводит к предположению, что процесс относится к дифференциальному снятию напряжения, которое существует, как известно, вследствие октаэдрического-тетраздрического несовмещения. Образование осколков представляет добавочную поверхностную площадь для удаления ионов и может повлиять на скорость образования вермикулита.
