CHARACTERIZATION OF ALUMINA POWDER USING MULTIPLE SMALL-ANGLE NEUTRON-SCATTERING .2. EXPERIMENT

Small-angle neutron scattering techniques developed in the preceding paper 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.
