Notizen:
In an earlier communication by the authors it was shown that the stack height distribution in a raw carbon black followed an exponential law. Extension of these studies to a heat-treated (2000°C) black showed that the exponential law is still valid when stacking is extensive. The exponential law and the effect of heat-treatment are explained by the existence in blacks of extensive stratification rather than the presence of short stacks of small layers. Evidently heat-treatment results in annealing of the strata to yield uniform layer domains and more ordered stacking. Simple expressions are derived for calculating the profiles of the 00l reflections and the coefficient of the exponent.
