Small-angle X-ray scattering (SAXS) and transmission electron microscopy image analysis experiments on a series of commercially available carbon blacks verify recent computer modeling results on scattering by mass fractal aggregates of globular particles. The authors show that the derivative of I(q) vs q SAXS data demonstrates a crossover point q{sub c} between surface scattering by primary particles and scattering by mass fractal aggregates. This crossover point is related to the mean diameter and the size distribution of the primary particles.
