Abstract Smectite can dramatically reduce the strength of crustal faults and may cause creep on natural without great earthquakes; however, frictional mechanism remains unexplained. Here, our shear experiments reveal systematic increase in with ionic radius interlayer cations among lithium-, sodium-, potassium-, rubidium-, cesium-montmorillonites, a smectite commonly found faults. Using density...

High specific surface area, large micropore volume, concentration of acid sites, and increased density sorption sites make montmorillonite pillared as an excellent adsorbent catalyst to remove contaminants from wastewater. The studies are aimed at establishing the adsorption catalytic activity Fe based on Krantau Navbakhor bentonite in relation dyes solutions. It has been shown that introductio...

Rehydroxylization of the anhydrous modification of dioctahedral montmorillonites can be carried out under DTA conditions with controlled atmosphere techniques. The structural character of the rehydrate prepared in this way is determined from X-ray and DTA data. The mechanism of the reactions by which the rehydrate can be formed is also considered. Thermal analysis curves of the rehydrate form o...

Base-exchange determinations were made on selected clays of the montmorill0niteillite group to test this method as an analytical tool for the analysis of mixed-layer aggregates. The relatively rapid manganese method developed by Bower and Truog was used and its precision determined oll monodisperse, monomineralic fractions and monodisperse fractions of prepared mixtures of illite and montmorill...
