Small‐angle neutron scattering techniques developed in the preceding paper [Berk & Hardman‐Rhyne (1985). J. Appl. Cryst. 18 , 467–472] are used to obtain microstructural parameters of high‐purity alumina powder. The values of the particle size, volume fraction and surface area have been obtained and are compared to data from techniques such as laser light scattering, X‐ray sedigraph and scanning electron microscopy. The particles exhibit a log–normal distribution and are spherical in shape with a mean particle size of 342 nm determined from SANS analyses of both beam broadening and Porod regions.
