11. The crystallite are typically not at equilibrium and they may contain different equilibrium crystalline state. 12. Such a phase comprises all the crystallites in the sample with the same crystal structure. 13. The higher water content compared to boehmite can be explained by a smaller crystallite size. 14. Such annealing also crystallizes BN, the size of the crystallites increasing with the annealing temperature. 15. The diameters of the individual crystallites in HOPG are typically in the range 1 10 ?m 16. Some titanium atoms in these crystallites react with organoaluminum cocatalysts with the formation of Ti C bonds. 17. Dispersion increases with decreasing crystallite size and approaches unity at a crystallite diameter of about 1 nm. 18. Dispersion increases with decreasing crystallite size and approaches unity at a crystallite diameter of about 1 nm. 19. Light tends to scatter as it crosses the boundaries between crystallites and the amorphous regions between them. 20. There is an ambiguity with powder grains : a powder grain can be made of several crystallites .
