Various dehydroxylated micas and rectorites were acid-treated. Rectorite-type mixed-layer mineral was formed from 2M1 and 2M2 mica and random mixed-layer mineral from 1M and 1Md mica. Rectorite was formed again from dehydroxylated rectorite. The rehydration and rehydroxylation properties of dehydroxylated rectorite and 2M sericites were found to be similar.

Résumé

Résumé

On a traité en milieu acide plusieurs micas et rectorites deshydroxylés. Le minéral interstratifié du type rectorite était formé de mica 2M1 et 2M2 et le minéral interstratifié au hasard, de mica 1M et 1Md. La rectorite s’est reformée à partir de la rectorite deshydroxylée. Il a été montré que les propriétés de rehydratation et rehydroxylation de la rectorite et des séricites 2M deshydroxylées étaient semblables.

Kurzreferat

Kurzreferat

Verschiedene dehydroxylierte Glimmer und Rektorite wurden mit Säure behandelt. Wechsellagerungsminerale vom Rektorittyp wurden aus 2M1- und 2M2-Glimmer und zufällig wechselgelagerte Minerale aus 1M- und 1Md-Glimmer gebildet. Rektorit wurde wiederum aus dehydroxyliertem Rektorit gebildet. Die Rehydratisierungs- und Rehydroxylisierungseigenschaften des dehydroxylierren Rektorits und der 2M-Sericite wurden für ähnlich befunden.

Резюме

Резюме

Разные дегидроксилированные слюды и ректориты перерабатываются кислотой. Из слюд 2М1 и 2М2 образовался минерал типа ректорита, состоящий из чередованных пластовразного происхождения, а из слюды 1М и 1Мd-минерал с произвольно смешанной прослой-кой. Из дегидроксилированного ректорита вновь образовался ректорит. Характеристикирегидратации и регидроксилирования дегидроксилированного ректорита и 2М серицитовоказались аналогичными.
