Abstract
An X-ray approach to analyzing ultradisperse systems is suggested. The approach is based on the simulation of diffraction patterns from an ensemble of nanoparticles with a given structure, size, and shape, including intensity calculations at each profile point. A program for calculations was developed. Its possibilities were demonstrated for the example of studies of samples prepared by solid-state oxidative thermolysis of iron oxalate dihydrate. The size of sample crystallites (coherent scattering regions) did not exceed 1–2 nm.
