Vast majority of published works describe the freeze-drying and ultrasonication that belong to the most frequently employed treatments. These techniques were used in shaping up the final properties of montmorillonite materials modified by inorganic or organic intercalation. The freeze-drying and ultrasound pretreatments have been shown to greatly affect the appearance of the PXRD (powdered montmorillonite) patterns of randomly oriented montmorillonite samples. Both treatments lead to the disruption of larger clay agglomerates into finer, more prone to mutual self orientation particles, but sonication even mild, constitutes a more efficient means of clay disintegration and induces greater textural ordering.
