A possible reason for activation of both mechanisms of agglomerate disintegration can be the effect of simple shear under high pressure (500-800 Pa) and sign-alternating character of plastic deformation in the course of ECMAE.
For example, in Figure 1, similar nodes are combined in the 1st iteration and node [n.sub.6] has two connections to the agglomerated node of [n.sub.4] and [n.sub.5] and has one connection to the agglomerated node of [n.sub.7] and [n.sub.8], so that [n.sub.6] is more likely to agglomerate with [n.sub.5] and [n.sub.4].
The Morphologi G3-ID extends the capabilities of image analysis by applying the technique of Morphologically Directed Raman Spectroscopy to enable the chemical identification of multi-component agglomerates that cannot be reliably classified on the basis of size and shape alone.
A cork agglomerate laminated with a polymer membrane (chemical base-copolymer polyamide (COPA)) with 105 g x [m.sup.-2] and 0.62 mm thickness was used in this work (Figure 1).
In Figure 2 the part of ACM image (1 x 1 [micro][m.sup.2]) for the Fe25 glass surface, where there is no agglomerates, is presented and one can see that the typical dendrite (for two interpenetrated phases) structure exists there.
Thus, in many laser diffraction methods, the results reflect the size of the primary particles, but agglomerates are not detected, as they are dispersed by adding pressure, ultrasound or stirring.
In general, aggregates and agglomerates have lower circularity than primary particles, and can be distinguished from them on this basis.
Two modes of dispersion are identified: the bulk rupture (an abrupt breakage of the agglomerate into multiple large fragments) and erosion (a sequential removal of small fragments from the agglomerate periphery) (figure 2).
Note that particle and agglomerate numbers on sieves decline with decreasing clay percentages.
The pure ibuprofen suspension (in 1% CMC) and ibuprofen agglomerate suspension (in 1% CMC) were given orally.
The agglomerate density is a good indicator of the dispersion of agglomerates into the polymer matrix.
