TEM Characterization of Pillared Rectorites
Abstract
High resolution and analytical methods of electron microscopy have been used to characterize a sample of natural rectorite before and after pillaring with Al203-clusters. The regular 1:1 interstratification of mica-like and montmorillonite-like layers yield (variable) interlayer spacings of about 28Å. Nonuniform pillar distributions have been attributed to layer charge heterogeneity and to pillar deformation. Other defects, like stacking faults, layer termination edges, and bent stacks were characterized by electron diffraction. The true chemical composition was determined by EDS on the basis of crystal-by-crystal analysis.
