From swelling and surface area measurements, it was found that the swelling of a montmorillonite depends linearly on the fraction of its layers that fully expand in water and that this fraction, in turn, depends linearly on the b dimension of the unit cell. Therefore, swelling is a linear function of the b dimension. However, the specific surface area of a montmorillonite is a linear function of its b dimension only if no partially expanded layers exist. It was also found that the distance between fully expanded layers at a given applied pressure is the same for all montmorillonites.

Резюме

Резюме

С помощью измерения разбухания и поверхностной площади было обнаружено, что разбухание монтмориллонита линейно зависит от той части слоев, которые полностью расширяются в воде и что эта часть слоев в свою очередь линейно зависит от размера b элементарной ячейки. Таким образом, разбухание является линейной функцией размера b. Однако удельная площадь поверхности монтмориллонита является линейной функцией его размера b, если только отсутствуют частично расширяющиеся слои. Было обнаружено также,что расстояние между полностью расширенными слоями при данном приложенном давлении одинаково для всех монтмориллонитов.

Kurzreferat

Kurzreferat

Von Quell-und Oberflächenmessungen wurde herausgefunden,daß das Montmorillonitquellen von dem Anteil seiner Schicht abhängt,der sich in Wasser voll ausdehnt und,daß die Größe dieses Anteils in linearischer Weise von der b Dimension der Einzelzelle abhängt. Deshalb ist das Quellen eine lineare Funktion der b Dimension. Die spezifische Oberfläche eines Montmorilloniten jedoch, hängt von der b Dimension allein ab, wenn keine teilweise ausgedehnten Schichten existieren. Es wurde auch gefunden, daß der Abstand zwischen voll ausgedehnten Schichten bei jedem gegebenen Druck für alle Montmorilloniten derselbe ist.

Résumé

Résumé

On a constaté à partir du gonflement et des mesures de la surface externe que le gonflement d'une montmorillonite dépendait de manière linéaire de la fraction de ses couches se dilatant totalement dans l'eau, et que cette fraction à son tour dépendait de manière linéaire de la dimension b de la maille. Le gonflement est par conséquent une fonction linéaire de la dimension b. La surface externe spécifique d'une montmorillonite n'est cepen3ant une fonction linéaire de sa dimension b que s'il n'existe pas de couches partiellement dilatées. On a aussi trouvé que la distance entre les couches totalement dilatées à une pression donnée est la même pour toutes les montmorillonites.
