An analysis of the three-dimensional correlation function of small-angle scattering is applied for the direct determination
of stereological parameters of hectorite samples. Beside characteristic lengths and volume fractions the specific order distances
are given. The samples can be described by homogeneous particles of different order magnitudes up to the size of the secondary
particles, which were estimated to have maximum dimensions of about 450 nm. Beside traditional stereological formulas, including
the interpretation of the derivatives of the small-angle correlation function, the so-called transformed correlation function
is applied in order to detect distinctive characteristic lengths.
