The contributions of grain facet reflectivity and scattering from the bulk of a grain of highly absorbing material were calculated as a function of sample characteristics. To test these results, the scattering intensity of a grain of microporous ThO2 was experimentally characterized by small-angle X-ray scattering using a synchrotron source. In addition, a new experimental method to probe the porous texture of nanoporous powders of highly absorbing compounds using a laboratory X-ray instrument has been proposed.
