Crystallites

 

small crystals lacking a clearly defined (faceted) form. Crystallites are found as crystalline granules in various polycrystalline formations, including metal ingots, rocks, and minerals.

Accordingly, it can be concluded that GL-GNPs thickens the small PA 12 crystallites and improves their degree of perfection, but it has negligible effect on the size and perfection of large-sized crystals that constitute most of the PA 12 [gamma]-form crystals.
The crystallite size and microstrain in powdered particles can be determined through X-ray diffraction peak broadening.
The average slab length and layer number of the MoS2 crystallites in the catalyst are 2.6 nm and 2.3, respectively, indicating the high dispersion of active metal species in catalyst.
Plucking was found to occur when the crystallites were separated from each other.
Where d is the average crystallite size (nm); k is the shape factor (0.89); [lambda] is the wavelength (0.15406 nm for the Cu-Ka radiation); [beta] (in radians) is the FWHM (full width at half maximum) of the main peak.
The crystallite sizes ([d.sub.RX]) for the as-prepared samples were determined (by measuring the broadening of the most intense peak of the phase in a diffraction pattern for the as-prepared samples) according to Debye-Scherrer equation as follows:
Figure 2(b) also shows that the preferred orientation of the crystallites in the hexagonal CdS phase is in the (002) crystal plane.
X-ray diffraction shows that the synthesized ZnO nanoparticles have hexagonal crystal structure with an average crystallite size of 29 nm.
Ni-SDC propose to be appropriate anode material to attain high performance because better output for anode materials require large triple phase boundary (where chemical reaction take place), fine crystallite size and proper porosity [7].
The bands appearing at 873 [cm.sub.1] reveal the presence of carbonate ions in the resultant HA crystallites due to the interaction between HA and ambient C[O.sub.2] in the processing.
