Abstract: The purpose of this study was to characterize more fully the surface charge characteristics of the end-member smectite in illite-smectite (I-S) mixed-layer phases found previously in pelitic...
Several soil and reference smectites and vermiculites and one reference illite were examined by high-resolution transmission electron microscopy (HRTEM) to decipher the nanostructure and layer charge ...

Abstract: The heterogeneity of sites for Ca→K exchange was examined by microcalorimetry in the <0.2-&micro;m fractions of some selected smectites. Six groups of sites, ranging in exothermic exchange e...
Measurements of the differential heats of K-Ca exchange are used to show that 6 groups of sites (ranging from −13.8 to −5.1 kJ/eq and with as many as 4 in any one sample) exist in kaolins ...
Layer Charge Heterogeneity in Vermiculites     Alkylammonium  Layer charge  Vermiculite  Weathering       font style='font-size:12px;'> 2012/2/7
The broad charge heterogeneity typical of nearly all smectites is not necessarily characteristic of vermiculites. In addition to vermiculites with pronounced heterogeneity, minerals with no or only li...
