X-ray diffraction patterns for mixed-layer kaolinite-glycerine-saturated montmorillonite were calculated, taking into account the differences of scattering power of kaolinite and montmorillonite layers. The data were compared with the experimental results for two kaolinite-montmorillonite mixed-layer minerals. The probability parameters and the total number of layers in crystals were established.

Résumé

Résumé

Les diagrammes de diffraction X d’interstratifiés kaolinite-montmorillonite saturée de glycérol ont été calculés en tenant compte des différences des pouvoirs diffusants des couches de kaolinite et de montmorillonite. Ces données ont été comparées avec les résultats expérimentaux fournis par deux interstratifiés kaolinite-montmorillonite. On a pu ainsi déterminer la probabilité d’apparition et le nombre total de feuillets dans les cristaux.

Kurzreferat

Kurzreferat

Es wurden die Röntgenbeugungsbilder für gemischte Schichten von Kaolinit, Glyzerin und gesättigtem Montmorrillonit berechnet, wobei die unterschiedlichen Streuleistungen der Kaolinit-und Montmorillonitschichten berücksichtigt wurden. Die errechneten Werte wurden mit den Versuchsergebnissen für zwei gemischte Kaolinit- und Montmorillonitgesteine verglichen. Es wurden die Wahrscheinlichkeitsparameter und die Gesamtzahl der Schichten in den Kristallen bestimmt.

Резюме

Резюме

Оценивались диффракционные картины рентгенограмм каолинита смешанного наслоения и насыщенного глицерином монтмориллонита, принимая во внимание различные рассеивающие способности слоев каолинита и монтмориллонита. Полученные данные сравнивались с результатами экспериментов с двумя минералами смешанного наслоения: каолинита и монтмориллонита.
