Different approaches to the analysis of Small Angle X-ray Scattering experiments on the porous aluminum-hydroxide pseudo-boehmite are compared. Experimental data is analyzed both as scattering from mass fractal aggregates and polydisperse collections of anisotropic particles. Both types of analysis are able to describe the data and provide specific surface areas in agreement with BET values obtained by nitrogen adsorption data. Clear evidence for a model involving anisotropic particles was obtained by combining the scattering data with transmission electron microscopy and nitrogen adsorption experiments.
