The histograms related to the size distribution of equivalent diameters (i.e., the size) and roundness (or the shape) of MC15A and MCNM are represented in Fig.
2, MCI5A, MC20A, and MCNM samples possess almost spherical morphology with average diameters of 25 to 40 pm being equal or close to those of the MC00 (images b, c, d and a, respectively).
The two-dimensional diffraction patterns in each of the 121 grid points were analyzed automatically to obtain the intensity maps in two 2[theta] ranges for MCI5A, MCNM, and MC20A (Fig.
Only in the case of MCNM, there exist two domains with very high concentration of MMT with coordinates Z9-X10 and Z8-X9.
For MCNM and MC20A the selected levels were Z8 and Z3, respectively.
Typical results from bright field transmission microscopy representing the average size and shape distributions for MC15A and MCNM with about 1 wt% of the respective MMT.
