Formatted abstract
Clay particles build (3-D) structured network within the aqueous suspension. Such a network prevents aggregates from settling under gravity force. It also immobilize (retain) water within a structure producing stable gel. 

To better understand this phenomenon, a microstructural investigation was conducted on Wyoming montmorillonite clay suspension which was gelled by aluminium chlorohydrate. Gel morphology was studied with aid of the synchrotron-powered transmission x-ray microscope (TXM) and cryogenic scanning electron microscope (Cryo-SEM).

New type of globular micro-morphology and the particle space arrangement was observed. For the first time, globular micro-aggregate morphology was found where flexible smectite flakes were curled to build globular aggregates. These aggregates were assembled onto multilayer, micelle-like globular superstructure. This new smectite gel micro- morphology may be similar to earlier described pseudoglobular microstructure model observed in eluvial and hydrothermal clay deposits.
